The feature (also a bug fix) being discussed here concerns the final
client-side step of the SCRAM protocol. Basically, it computes a
challenge from the server and packs the answer into an outgoing reply.

No reason to. We can keep it internal (the "final step" function, that
is) and backport its logic, its helpers, and all (two-ish?) public
functions that call it (I'm likely adding a third).

Alternatively, we could

- have ERC restrict this feature to users of Emacs 29+, or
- stick with the status quo and manage this particular case manually via
  erc-comapt.el [1].

I'd be fine with any of the above, really.
