1) Should we deprecate SHA1 in signatures? (Or did we already?)

This would break all existing signatures for no good reason.  Instead a
new v5 key format MUST NOT be used with signatures "weaker" than
SHA-256.

It is up to an implementation to decide what to do with old keys and
signature material.  The question is related to the old question what to
do with an expired or revoked signature key: are all signatures are then
suddenly untrustworthy or is there enough external context which allows
to decide that the signed document is still intact?
