Today. The point was at some point Heimdal and/or MIT will get cred cache 
in keyring support.

Except you're ignoring the part where I asserted you don't need RxRPC to 
use keyrings and hence can get rid of the PAGs without it. So either tell 
me I'm wrong and why, or answer the question I asked.

Not really. It's trivial to ignore the groups-encoded-PAGs mechanism.

So you described more complexity. Ok. Want to tell me what the *benefits* 
are now? ;-)
