I don't think the decisions on what does and doesn't belong should be
based on names.  FWIW, I don't see in xref.el anything that doesn't
belong there.

My sense is that xref (and tags before it) suggests existence of an
index and that xref- operations are then driven by that index.  Not
by taking entries out of that index and extracting file paths.  That is
the role of project.  Project supplies only a set of files.  After that
regex-based algorithms seem entirely expected.
