So long as you understand GnuPG will not make any changes that break RFC
conformance... and dropping SHA1/3DES breaks RFC conformance.

Everyone agrees. GnuPG for many years has defaulted to AES. 3DES
exists for RFC conformance. We've migrated away from 3DES as far as we
can; any further requires a change to the RFC.

This opinion is not shared by the cryptanalytic community as a whole.
We are nowhere near a break in 3DES.

We're already in the working group trying to push this forward.

The WG has a mailing list where these things are discussed. Also, many
WG members have private asides with other WG members.
