I realize it all sounds very natural to you, Dmitry, because you designed it.
However, accept that is not as natural to everyone else.  I too want a command
that lets me immediately jump to the first hit, rather than populating a very
large search results list only to visit it.  There is value in
tags-query-replace.

The fact that the xref.el API makes this now hard to do is a deficiency in
that API, not an indication that we shouldn't be doing it. Let's fix the API
-- which is still considered experimental. Your generator suggestion sounds
like a good approach.
