+1 This is important for me. I would like to make `sly-mode' use
`xref` when it's available.
`sly-mode` is a minor mode active in many buffers of different major modes,
all part of the SLY family. Xref should use the same backend in all of them.

Can't see right how I can use this to solve my particular case, but
I'm confident
I will :-)
