I noticed this myself, and Wireguard configured with systemd doesn't create a link-local address by default either. However, you can just create a random link-local address yourself and set that on the interface directly.

Issue description
I have multiple Wireguard tunnels that I am in the process of switching to IPv6 connectivity. As they are only point-to-point tunnels I intend to use the IPv6 link-local address of the Wireguard Interfaces to route my traffic. This works fine on my VyOS routers, but trying to connect my 1 UGW3 I noticed that the Wireguard Interfaces don't receive a IPv6 link-local address, even though all of my other interfaces do.
I don't see any option to enable this in the config and it also doesn't receive one, when I explicitly assign the Interface an IPv6 ULA. I could use IPv6 ULAs to route the traffic to the UGW3, but I think not receiving a link-local address is a bug as Wireguard interfaces on all of my other systems receive a link-local address.
