I can see some corner cases where your concerns would be a problem, but in
general, cp does exactly what I want, and having to do a bunch of additional
checks is just annoying. And while I can definitely believe that there are
programs where race conditions would be a concern or where it could be
problematic to assume that the target is a directory, I've never personally
written or worked on a program where that was a concern.

Requiring a terminating directory separator would be annoying, but having
separate functions where one requires that the target be a file and the other
is more liberal does make sense.
