I just tried

   (setq xref-show-definitions-function 'xref-show-definitions-completing-read)

To enable what seems to be the only table in Emacs core that has this
feature with fido-vertical-mode.

It seemed to do the right thing, prepending each entry with the name of
its associated "group".  Is this what it means to support this?  If so,
I'll close.  Else, please explain what support you're looking for.

Thanks,
João
