Multicast over a wireguard link?

[Toke Høiland-Jørgensen]

Does Wireguard has a notion of multicast? I would like to eventually
replace my current VPN setup with wireguard. I currently run Tinc in
switch (layer 2) mode, and run the Babel routing protocol on top.

Babel announces itself via link-local multicast to everyone on the link.
Does this work with wireguard? I guess the equivalent semantics would be
"send this packet to all known peers"...
