Those ciphersuites are not ideal, but exploiting padding oracles
requires an auto-reconnecting client and doesn't buy you all that
much.

I think the direction upstream is going with SCRAM (or similar) is
fine, but either new hashes are required or using a customized code
base that uses MD5(password|username) where the password would
normally be directly input is needed.

I don't have time to write any code, but I'm happy to review schemes
and code (and probably will at some point anyway).
