project-rgrep sounds just as good to me (M-x grep is flat).

Would grep-project, in your view, use the xref interface? If not, 
they're not the same either.

On the other hand, M-x project-<tab> won't. And the user won't be able 
to discover all core commands that work on the current project.

Both problems should be solved by making execute-extended-command use a 
new completion category that would perform laxer matching.

It's the purpose of the API. Nothing says we can't provide some commands 
that use the API together with it.

We could move them to a yet-another package is that's the consensus, but 
there is value in keeping them together.

Not every project command is going to have a "normal" counterpart.
