This was pure future-proofing and I'm fairly sure it doesn't apply to any
existing mechanisms.  In other words, I think we can safely ignore this
for now and come back to it as new SASL mechanisms are introduced, if
someone introduces one with a large initial response.

Given the restrictions in other protocols, I think this is probably
unlikely to happen.
