Also, t2022.3 has me very confused. It is explicitly checking that if we have "subdir/foo" unmerged in the index, and we "git checkout $tree -- subdir", and $tree does not mention "foo", that we _leave_ foo in place. That seems very counter-intuitive to me. If you asked to make "subdir" look like $tree, then we should clobber it. That change comes from e721c15 (checkout: avoid unnecessary match_pathspec calls, 2013-03-27), where it is mentioned as a _bugfix_. That in turn references 0a1283b (checkout $tree $path: do not clobber local changes in $path not in $tree, 2011-09-30), which explicitly goes against the goal we are talking about here. It is not "make my index and working tree look like $tree" at all. So now I'm doubly confused about what we want to do. If we want to retain that behavior, I think we can still cover these cases by marking items missing from $tree as "to remove" during the diff/"update the index" phase, and then being more gentle with "to remove" files (e.g., not clobbering changed worktree files unless "-f" is given). I am not sure that provides a sane user experience, though. Why is it OK to clobber local changes to a file if we are replacing it with other content, but _not_ if we are replacing it with nothing? Either the content we are losing is valuable or not, but it has nothing to do with what we are replacing. And Junio argued in the thread linked elsewhere that the point of "git checkout $tree -- $path" is to clobber what is in $path, which I would agree with. I think the argument made in 0a1283b is that "git checkout $tree $path" is not "make $path like $tree", but rather "pick bits of $path out of $tree". Which would mean this whole deletion thing we are talking about is completely contrary to that.
