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.
