Hard to parse the networking jargon, but does this enable offline connections?
If I have two devices on my local LAN (both connected to a Tailnet) and my home internet goes, currently the devices disconnect from each other. I have been looking for a way to prevent that, so that the all devices connected to the same WiFi network on a tailnet can find each other even if the internet connection to the wider world is broken.

You might be able to solve this by hosting your own control plane such as Headscale. Instead of having Tailscale manage/coordinate all the nodes on tailnet.

I ran headscale for a while and can confirm local devices could still chat when the internet went down.
That'd be easy if only wireguard supported multiple endpoints per peer, then one could add the ULA address of the local devices in addition to the external one.
that already works
Not for me. Maybe some misconfiguration on my part then.
run `tailscale status` and ensure that your local machines are connected to each other `direct` and not using a relay.
