Note that presently the emacs add-on packaging guidelines do demand
separate sub-packages for the elisp files. However a number of
packages do exactly as you've done. I am in the process of reviewing
and reworking the emacs packaging guidelines and the next iteration in
that process (after the currently proposed revision - see
fedora-packaging list) will be to propose a guideline to deal with
this situation more pragmatically.

When a package adds a one or two elisp files, it does seem like
overkill to force them into a subpackage, IMO. Certainly Debian has an
exception for this case allowing them to be installed without
requiring emacs (which then forces a directory ownership as you
describe).

At the moment I'm thinking that the best approach is a variant of the
above, where a package can install files into
%{_datadir}/emacs/site-lisp/foo without requiring emacs, and so it
will own %{_datadir}/emacs/site-lisp/foo, but not
%{_datadir}/emacs/site-lisp/
