Actually, we have more than 2: we also have the cl-lib/cl-macs
dialect, and then we have the cl-defgeneric dialect, the pcase
dialect, and probably a few more.  They all look like different
programming languages to me, but that doesn't seem to bother anyone,
and we aren't going to evict any of them in favor of others any time
soon, are we?

Recommendations should be documented as such (and we have quite a few
of them in our manuals), and perhaps flagged by checkdoc and other
similar linting tools, but warning about them is IMO inappropriate.

Yes, and why isn't that enough?
