"some"?  Do you have exceptions in mind?

Probably.  But that would suggest that the place to improve the doc
is for diff.noprefix configuration variable, no?

As it is a plumbing command behind "add -p", "am", and friends, I
would hate to see "git apply" pretend to be smarter than its users.
When the user tells it to use -p0, it shouldn't guess, and when the
user tells it to use -p1 by not giving any -p$n, it shouldn't guess.

As long as we make it clear "git apply" without any explicit -p$n
means the user is telling it to do -p1 in its documentation, I think
it would be fine.

I share the same feeling ;-)  But the boat has sailed, so the best
we could do is to warn in its doc (i.e. where diff.noprefix is
described) about its pitfalls.
