I would be very interested to hear what you are using it for, as via tailscale would rule out many of Haven's obvious use-cases.

The short answer, mainly cuz I wanted to see if I could. And that it saves my notes, and the blastr function works. Outside of that I won’t be able to use Blossom, and I never really planned on other users using it.
The longer answer gets in to why I use Umbrel in the first place (simplicity has a lot to do with it) and why I didn’t want to use the prepackaged relay on the Umbrel store.
