You can do that though? Tailscale can as well. A device can advertise subnets, and can route them through tailscale, so you just need a single node in a LAN.

This is still L3 layer though. One the main use case of L2 is proper DHCP propagation and avoid subnet collisions. I do not think that this matters in practices though. Only a limited amount of user facing service require proper L2 emulation (apple TVs ?)
Or anything that uses multicast. The idea is you want homoiconic networking behavior and portability between local and remote. Hacking in special routing and subnets in L3 doesn’t give you that.
