This indeed seems like the most important prerequisite, because the
command-line options accepted by Universal ctags are incompatible with
those of etags, so supporting both would be a pain.

You mean, if we want to support tools beyond Universal ctags?
(Because the latter supports Emacs-compatible TAGS output.)  Yes, if
we want to support other tools, we'd need to extend etags.el or rely
on external packages for parsing their tags tables.  E.g. GNU Global
doesn't support TAGS format even as an option, AFAIK.
