I did it in *scratch*. But *scratch*'s major mode is not
emacs-lisp-mode, it's lisp-interaction-mode. I think the difference
is significant for the purposes of this discussion.

Isn't it possible to _prefer_ the symbols that are consistent with the
major mode, but not entirely discard the other possible candidates?
In a mixed-language project such as Emacs, these subtle conditions
that completely conceal symbols depending on the current mode, make
very little sense to me. (And there are other mixed-language projects
out there, like Guile, GDB, etc.) The Emacs TAGS tables traditionally
included tags from lisp/ files in src/TAGS, and for a very good
reason.

I assume that this new facility is an improvement, so I _want_ to use
it. Especially since NEWS says:
** etags
As a result of the above, these commands are now obsolete:
`find-tag-other-window', `find-tag-other-frame', `find-tag-regexp',
`tags-apropos' and `tags-loop-continue'.
Considering something obsolete means that a replacement is available
that is as good or better than the replaced feature. I don't want to
go back to obsolete commands, unless I really have to, i.e. unless I
find the situation with xref unbearable. I hope we are not there yet.
> Alternatively, you could reset `xref-find-function' and `xref-identifier-completion-table-function' to their default values in `emacs-lisp-mode-hook'. That could be a decent choice if your TAGS file includes the lisp files as well.
See above: out src/TAGS includes lisp/TAGS. We do this for a long
time, and it's a tremendously useful thing when working on Emacs
development.
