Not really, no.  We could refrain from providing a default
implementation, and instead add a method to `cl-no-next-method` or
something like that, but I'm not sure it would make much difference.

But we could use some dynamically-scoped
`project--within-roots-fallback` variable to break such recursion ;-)
