There was a very long discussion about, see
<http://thread.gmane.org/gmane.emacs.devel/87506/focus=87506>

In short:

Tramp uses file-remote-p internally. OK, this could be replaced by an
internal function.

Other packages use it as well, inside and outside core Emacs. We didn't
want to propagate tramp-* functions outside Tramp; file-remote-p is the
check to be used when necessary. Not so important for basic file name
operations, but needed for all process related things.
