Replying to [comment:14 nickm]:
> I don't think we can do decaf encoding on ed25519 identities: they are
already published in descriptors and interpreted widely. For hidden
services and decaf, I don't know how hard the transition would be. The
only place to change the encoding would be in .onion addresses, and I
don't know whether there's time/energy to do that in the current state of
prop224.
Happy to be overruled here, but, does this imply that we should stick to
the current encoding for onion addresses, since if we have to maintain two
different encodings forever, and other people building Tors will forever
need to build both kinds, that will make everybody sad?
