(Delete is a little bit different. Then we would need to pop up a warning dialog where there usually is no dialog at all. Maybe not ideal...) I think this is a good idea here as additional information/a reminder to the user. Even if core SVN has decided to omit it.

The lock is there to prevent a commit unless you have the lock.
svn:needs-lock is used to set the read-only state as a warning not to
waste your time editing the file without first getting the lock.
Delete and rename are somewhat different cases; without the lock you
cannot commit the delete or rename, but even if you go ahead and
delete a file in the WC and are then unable to commit, you have not
wasted a lot of effort. The only case I could come up with where
client side work is wasted is if you are doing some major renaming
work which you are then unable to commit.
