Ooh, intriguing.  Count me as another person who has resorted to
making my own helper tool for others to use (specific to our internal
repository, though, as it also figures out inter-module dependencies
to allow specifying only a few modules of interest while still
checking out everything needed to build those; but it'd be nice to
need less scripting to handle the git-related bits to actually
sparsify or densify).

Does it enable core.sparseCheckout in the current worktree, or for all
worktrees?  Do we require extensions.worktreeConfig to be set to true
first?  If we don't require extensions.worktreeConfig to be set to
true, and users add worktrees later, do they encounter negative
surprises (immediately or later)?

worktrees in combination with sparseCheckouts were a headache here
until I just forced people to manually first set
extensions.worktreeConfig to true before using my 'sparsify' script,
regardless of whether the user was currently using worktrees.  That
fixed the issues, but having to provide a long error message and
explanation of why I wanted users to set some special config first was
slightly annoying.

I wonder if 'git worktree' and maybe even 'git config' should
themselves have special handling for core.sparseCheckouts, because it
can be a real mess otherwise.

Nice.

The default of reading from stdin seems a bit unusual to me, and I
worry about having to explain that to users.  I'd rather the add
command took positional parameters (anything that doesn't start with a
hyphen) and added those, e.g.
  $ git sparse-checkout add '/myFolder/*' '
with the option of the user specifying --stdin.

Does it leave an empty sparse-checkout file around?  Also, what if
users have several paths defining their sparse pattern, and want to
temporarily get a full checkout and then come back -- do they need to
re-specify all the paths?  (Maybe this *is* the route we want to go;
I'm just trying to mention any possible negative effects we _might_
run into so we can consider them.  It's not quite as relevant in my
case since people specify a few toplevel modules and sparse-checkout
gets several entries auto-generated for them.)

Also, I'm particularly worried that a user with multiple worktrees,
both sparse, could run 'git sparse-checkout disable' in one and then
find that when they return to the other worktree they get a variety of
nasty surprises (e.g. accidental staging or committing of the deletion
of a huge number of files, random weird errors, or gradual and weird
de-sparsifying as various git commands are run).  This, of course, can
be averted by making sure core.sparseCheckout is set on a per-worktree
basis, but that seems to be something people only do after running
into problems several times unless some kind of tooling enforces it.

This has worried me for a while, even if it hasn't yet caused us
issues in practice.

Oh, um, would there be any option for fast but without grabbing
sibling and parent files of requested directories?  And could users
still request individual files (not with regex or pathspec, but fully
specifying the path) and still get the fast mode?

Basically, our sparse usage is exclusively specifying leading
directories or full pathnames of individual files, but we really want
the repo to feel smaller and make sure people notice at a glance.  We
have a huge 'modules/' directory, and want people to be able to get
just 15 of the 500 or so subdirectories that would appear in that
directory with a non-sparse checkout.  And similarly we want to be
able to grab just one or two files from a directory of many files.

Instead of trying to validate the sparse-checkout file everytime,
perhaps we want to change core.sparseCheckout from a boolean to a
tri-state or something where it specifies how to parse the
sparse-checkout file?  Or maybe when special directive (some form of
comment-looking line) appears at the top of sparse-checkout then we
use the hashsets speedup while disallowing general regexes and
pathspecs other than leading directories and full pathnames?

I'm not sure if that makes sense or not; just throwing it out there as an idea.

I'll try to get some time to look over these patches in the next few days.
