That would be simpler, yes. Proposed patch attached.

My impression is that distros generally prefer Universal Ctags these 
days, though you can use Exuberant Ctags if you're old-fashioned or 
Emacs ctags if your even older-fashioned. On Fedora, 'ctags' is 
Universal Ctags; on Ubuntu all three variants are available as options 
and /usr/bin/ctags is a symlink to /etc/alternatives/ctags which in turn 
can link to /usr/bin/ctags-universal or /usr/bin/ctags-exuberant or 
/usr/bin/ctags.emacs.

To some extent it's a chicken-and-egg problem: if we keep shipping ctags 
some distros will keep making it available as an option. But there's no 
real need for us to keep maintaining the third (and oldest) variant.
