Comment:

 Fine punting to 0.2.6. (The backport will be that it either works or it
 doesn't.)

 AFAICT, it doesn't do us any good to make the RSA link certificates longer
 unless we do it as part of some kind of effort like prop220.

 Argument: Since we're using an adequate EC group for our ECDHE, we get
 forward secrecy except against an active MITM. But any MITM that's enabled
 by RSA1024  would work just as well if we increased the link key size to
 2048 bits, since the identity key size is still RSA1024 until we implement
 proposal 220.
