I was amazed by the following proposal :
"A receiving agent SHOULD be able to verify signatures with keys up to 16384 bits".
If we drop it, then there is no guidance anymore.
Reasonably, for any implementation, today:
"A receiving agent SHOULD be able to verify signatures with keys up to 2048 bits".
This does not prevent any implementation to support larger key sizes.
