On the other hand, tighter integration might have its benefits, too. 
Otherwise, the user wouldn't be able to use the Emacs's TAGS files for 
navigation when working on, say, an ELPA checkout.

I'm not sure if somebody will really want to, but it makes sense to be 
able to use it both from core Elisp code, and third-party one equally.

The tags part of the emacs-lisp-mode's xref backend could bind etags 
vars locally based on the value of source-directory, instead of using 
the current tags-table-list.

That's a good question. Indeed, we could say I only had it built to see 
how tags work with Elisp.

However, I do occasionally use src/TAGS, and 'make tags' builds both files.
