Hello, relay operators!

I'm hoping to get some feedback from relay operators, particularly
those who use the MyFamily option, about the best way to deploy
proposal 321. You can read the proposal at:

https://gitlab.torproject.org/tpo/core/torspec/-/blob/master/proposals/321-happy-families.md

The main idea of this proposal is to provide an easier way for
relays to declare that they are in the same family. With proposal
321, each relay in the same family uses a cryptographic certificate
to prove that it is in the same family as the others.

One small clarification, since I know not everybody will read the proposal: this proposal is not only for making families easier to declare: it will also make them far more efficient to implement by saving significant amounts of bandwidth for client directory downloads. So even if everybody thinks that the current MyFamily configuration mechanism is perfectly easy and hassle-free (ha), we'd still probably want to implement something like this in order to make the network more efficient.

cheers,

Nick
