It's useful for a lot of people though (although nowhere near
most). People who're friends of a guy who's in a usergroup with a
guy who went to a conference that a developer went to who's also met
someone on the security team should theoretically be able to just say gpg
--somethingorother and get a list of the trust path, and a bright little
message that says `Hey, you have reason to trust this person, well done!'.

I don't know that gpg has such an option atm though, or whether the
keyservers are setup "appropriately" for such an operation to be really
feasible.

But there's little cost from our end to make it possible at least.

Not really possible. If one of the security team dies, or their equipment
gets stolen, or Quantum computing takes off, or... Heaps of things can
invalidate a key. The security one ought to last a few releases at least
though, enough so that manual reverification isn't too horrible.

Why would verifying a new security-key necessarily be significantly harder
than verifying a new unstable-key, though? In both cases you only really
want to check that its signed by the previous security-key.

A global index wouldn't be entirely appropriate for partial mirrors. *shrug*

How would you go about signing half of a global index with the unstable
key, and leaving the rest signed by the security key?

Having a new file right next to the old Packages.gz file might be
easier to ensure mirroring too. I'm not sure where you'd put a global,
signed index? *shrug*

You could have both, if you wanted, too, I guess. How would the index
be particularly more useful?

I don't speak for anyone save myself. GPG encrypted mail preferred.
