I have in mind xref-find-functions list of functions instead of
xref-find-function symbol. But that's tricky because you have
xref-identifier-at-point-function and
xref-identifier-completion-table-function and potentially many more
coming soon. Each of these should also be lists to allow for multiple

I think a more condensed system would serve us much better here. Instead
of the above 3 config vars use one - `xref-backends` holding a list of
backend names. Like '(elisp etags). Then dynamically expand each of them
as in `elisp-xref-find`, `eslip-xref-identifier-at-point` and
`elisp-xref-completion-table`. If some of the these are not defined use
the default.

Then the minor mode as I have just proposed would be trivial to
implement. I don't see a straightforward implementation based on the
current xref.
