xref-find-references won't search inside the current project root.
That's about all project-search-path is currently used for, but
hopefully other uses will crop up in the future. They would fail similarly.

Maybe if we have project-find-regexp-in-roots, it will only search
inside project-roots. And project-find-regexp will search inside roots +
search-path. It's unrelated to the issue above.

I've addressed that in the other message, I think.

One might call "always recursing" the "modern" mindset. For instance,
when calling Ag (a popular recent re-implementation of Grep), you have
to make extra effort *not* to recurse. There no corresponding option, even.

I hope you'll consider whether recursing is too harmful, in each case.

Not "rgrep". Instead of calling find constructed command-line arguments
once and collecting results, you'll have to call grep for each directory
you're interested in. And instead of find+grep, one could use Ag.

I'm sure it'll be more involved than the current implementation of
xref--rgrep-command.
