Just a thought ... since we've now got a way to indicate + and - with

will have a hint that in the next update the shorter keys will likely become
not so welcome and large keys more so?

   0 < key size < 511  : MUST NOT
 512 < key size < 1023 : SHOULD-
1024 < key size < 2048 : MUST
2049 < key size < 4096 : MAY

Beyond what Russ just pointed out, I find the first line to be in bad taste. Any IETF spec that says "you must not be able to verify a signature even though it is valid" is pretty offensive.

Can we return to talking about interoperability?
