I think so.
But maybe there's room for some fine-tuning here. I think it depends
on whether or not there is anything sensible the user can do with that
item (with status=not-present|absent|excluded).
The crux of the matter, according to me, is: I, as a user, need a way
to tell svn to do something with foo in wc.db, even if there is
another FOO on disk. If I'm specifically giving svn the target 'foo',
I really mean foo, not FOO. That goes for all 'foo' in wc.db on which
"actions" are sensible ... I'm not 100% sure if that includes
not-present|absent|excluded.
The main principle is: it shouldn't matter whether there is a FOO in
the way or not. Anything I can do with foo in wc.db, I should be able
to invoke regardless of the ondisk-presence of FOO. If that's not
possible, then there's really part of the wc.db that's unreachable for
me, and that's a problem.
While I was working on #3865, I thought it would be good enough to
merely check for any case-exact matches in wc.db. I still think that's
the easiest "heuristic", but maybe there's room for some further
thought here.

No, it's not:
- Both fOO and foo exist in wc.db.
- FOO is on disk.
- I invoke 'svn <subcommand> Foo':
1. Is there a case-exact match in wc.db? No
2. Ok, then apply truepath-ing: so the user is meaning FOO.
But the user can still do useful things to fOO and foo, if he gives
the exact correct casing.
