I agree, unfortunately this series does not help with git-restore, only 
git-switch. For restore on an index without conflicts I think it could 
just use the pathspec in struct unpack_trees_options and set = 
UNPACK_RESET_PROTECT_UNTRACKED but that does not help if we want to 
handle conflicted paths differently to non-conflicted paths.

I think it's fine for "checkout -f" to overwrite untracked files (and if 
"switch --discard-changes" does not then there is no pressing need to 
add such a mode to checkout), --force is a good name for an option that 
nukes everything that gets in it's way. For "reset --hard" I'm not so 
sure, if I have changes to an untracked file I don't wont them 
overwritten by default. There is no porcelain equivalent to "read-tree 
--reset --protect-untracked -u" and I was hoping "reset --hard" may 
become that porcelain equivalent with a new --force or 
--overwrite-untracked option.

For the various "foo --abort" some (most?) are using "reset --merge" 
which I think declines to overwrite untracked files but rebase uses 
"reset --hard" which I'd like to change to protect untracked files in 
the same way that rebase does for the initial checkout and when picking 
commits. I haven't thought about stash.

Best Wishes
