Having actually read the doc strings I see that xref backends are supposed to 
define `xref-backend-identifier-at-point` which can stuff any information it 
needs in a property of the string it returns, as sort of a semi-covert channel 
to `xref-backend-definitions` etc. Sorry about the unfounded complaint.

Would adding `xref-find-references-at-mouse` be handy for use in the context 
menu?
