So some possible outcomes are:

1) They do PGP/GPG and don't get compromised. Long term outcome: we
come out way ahead.

2) They do PGP/GPG and do get compromised. Long term outcome: we trust
bad things and lose, hopefully this gets spotted quickly and dealt with.

At a minimum this raises the bar for attackers when trying to insert a
fake release/whatever. The real problem however is the cost of doing
this. Key creation/storage/management/backup/etc is all non trivial
and not free. Is the cost of this worth it?

I think if we are going to push this we need to come up with a pretty
good set of guidelines that are easy to follow and implement. Things
like creation of keys, usage, storage, how to handle key roll overs,
lost keys, etc. Maybe even have a trusted party signs packages sent to
them, confirms the package with the project through some other trusted
channel like secure email or because they know the guy in real life/etc.
