It's because help-mode is not specialized enough. I think there should
be `elisp-help-mode`,  `describe-help-mode` etc. which are derived from
`help-mode`. Maybe obvious, but this struggle with the choice of the
default backend wouldn't be there if xref was able to merge backends.

(FWIW, I would also like to have elisp xref in info mode.)
