Yeah, "give --dry-run for anything potentially destructive" may be a
good general principle, although we'd need to know where to stop.
For example, I am not sure if "git reset --hard -n" would make all
that much sense, as the sole point of running "reset --hard" is "I
made an unrecoverable mess---get me back to a clean and known state
no matter what" and in that context, "let me see which files in the
working tree will be removed and checked out of the tree-ish and
which paths in the index records a different blob than what is in
the tree-ish, before deciding if I still want to stay in the
unrecoverable mess or I want to get out of it" is something you
could request, but at the same time, there is not much point in
actually asking it. Of course, a --dry-run that is not used often
simply because it is not all that useful in practice is fine to have
as long as it works correctly---I am saying that it's not something
I'd personally prioritize myself.
It would be an excellent addition to "restore-path" (and also to
"checkout [<tree-ish> [--]] pathspec") to give "--dry-run". Not
just because it is destructive, but because unlike "reset --hard",
it is selectively destructive. Having a way to make sure that the
given pathspec touches only the paths that the user intends to
recover from the tree-ish or the index would be valuable.
But it is a new feature, and I'd think it can (and probably should)
be done as a follow-on series outside the main series you have been
working on. Let's make sure that we have the basics ready by the
end of this cycle.
Thanks.
