Great news!

How will older clients deal with a certification signature from this unrecognized algorithm?

Yes, I intend to do this with the subkeys (Curve25519)
Only the primary (certification key) would use ed448 which would rarely be used and only offline.

Agreed  :-)
In this situation, I just want to avoid creating a new key-pair as long as possible and ed448 is likely to survive just a bit longer from what I understand.
Performance is irrelevant.
