Not exactly. xref-find-regexp is interested in all kinds of files, not
just source files. That includes, say, the README file at the top of the
project.

However, you raise an interesting point. Whereas xref-find-references
would like to search in all load-path directories, maybe it would be
enough if xref-find-regexp only searches inside the current "project
root", for some definition of that notion.
I wonder how we could make it work this way. Make "project root" an
orthogonal feature?

We can't rely on every Elisp project declaring a "project root" in the
same way, though.

VC is one option for this. Or the project may be not registered in any
VCS yet, and the root would be determined based on, say, the presence of
configure.ac. Again, this suggests that notions of "source directories"
and "project root" can be somewhat orthogonal.
On the other hand, after the project root is determined, it might want
to add some new element(s) to the source directories list.

Right. We'll need those pieces of metadata that are useful to more than
one subsystem, and can be employed in a general way. Though a generic
metadata storage might be useful as well: thus, if some minor mode has
read the project file and parsed the compiler options, it can set the
related metadata, so that code completion and linter could use it
without waiting for Emacs core to standardize it.

Mostly those major modes that can launch and interact with a smart
external process, I think. The rest (except for Elisp) will leave it to
minor modes.
