Yes I did, and I no longer support that either. For my setups it is local private ipv4 networks all the way now! How tailscale or other VPN deals with that is not my problem!
If two nodes are on different networks, they should not be allowed to talk to each other anyway. Seems like security risk! Clean design, simple rules!
We are so lucky people like you aren't in charge, or we wouldn't have the internet in the first place.
