This is an interesting scenario that I had not considered. Thanks!

My guess is that we should set `extensions.worktreeConfig=true` to
avoid surprises. I'll need to play with this to discover the answers
to these questions:

1. Where does the worktree look for the sparse-checkout file? Does
   each worktree have its own sparse-checkout file? Should it?

2. If I have `extensions.worktreeConfig=true` and `core.sparseCheckout=true`
   in the current worktree and run `git worktree add`, does the new worktree
   have `core.sparseCheckout=true`? Can we `git clone --sparse` and then
   start building sparse worktrees seamlessly?

I had the same thought, and likely that's where we should go with the
builtin. For our needs, the input over stdin is more important for
testing, so I built it first. I will adjust the CLI here to take a set
of paths over the arguments unless --stdin is given.

In this case, there is an intermediate step (that follows the existing
advice) to modify the sparse-checkout file to contain only "/*\n" then
run read-tree to fill the working directory before disabling the config
setting.

Perhaps "disable" is the wrong word to use, as it makes you think that
there should be an "enable" that can quickly toggle between the two
modes. Maybe instead it should be "git sparse-checkout reset [empty|full]"
where you could 'reset' the sparse-checkout to one of two initial
states:

1. empty: only files at root are included.
2. full: all files are included.

In each case, we would obliterate the existing sparse-checkout entries,
but hopefully that behavior is more clear from the command names.

Exact files could probably be included and still be fast. It requires an
extra hash check per entry, but that's a small price to pay I think.

With the sibling files, this is something I believe to be user-friendly:
as a user drills down into the folder they included recursively, there may
be helpful files along the way, like documentation, project files, etc.

Here is my philosophical position here: a repo can take advantage of the
sparse-checkout feature if it is properly componetized. Those component
boundaries are likely at folder boundaries. Any file that exists in a parent
folder for two components is likely important to _both_ components. If
a file is large and is not needed by both components, it should be placed
deeper in the tree, so it can be avoided.

With that philosophy in mind, I designed this to help users fall into the
"pit of success" when their repo is in a good shape AND to motivate users
with repos in non-optimal shapes to reorganize.

The thought I had about exact file names is similar: if there is a large
list of files in a folder where I only need a subset, then how do I know
if a new file is added that I need? It will not show up in the directory
without updating the sparse-checkout. A user would discover this need by
something going wrong when they are not interacting with version control:
a build.

This is particularly important with the root directory. We need things
like .gitignore, .gitattributes, README, LICENSE, etc. to be populated
by default. If there are too many files at root to reasonably work with
the repo, then the repo should be reorganized using folders.

Your modules/ example seems to work with the feature as designed, as
you want a set of folders one level deeper. Grabbing one or two files
from a directory is a direction we can go with the feature, but I will
continue to believe that should be a rare occurrence compared to including
a folder recursively.

In this series, I turn `core.sparseCheckout` into a tri-state, and only
try to validate the sparse-checkout when `core.sparseCheckout=cone`.
This avoids spending time on the validation when someone is content using
the existing feature.

The _intent_ of using the sparse-checkout file and no extra data structure
was to let other clients (or an older client) read the sparse-checkout data
and result in the same working directory. One thing I realized after
submitting is that the tri-state config variable will cause old clients
to error on parsing the non-boolean value. Instead, in v2 I will introduce
a new boolean config variable "core.sparseCheckoutCone" that will do the
same thing as the current series when `core.sparseCheckout=cone` and will
fix this compat scenario.

I look forward to your feedback! I also have some feedback to respond to
from my team [1], but I'm waiting to make sure the community likes the
overall idea before jumping into code style and method organization
details.

Thanks,
