Sure!, definitely worth exploring, e.g. it would be fun to think about
DTLS/SRTP alternatives for WebRTC.

It would be easy to link something from the Wiki if you had a draft.

I haven't looked at this part of WireGuard that much, so I'm not sure
what else might be needed (e.g., how do you deal with packet loss
during handshake?).

Of course you should talk to WireGuard about their experiences, and
see if this could align with them and be useful for them, too.
