Well, Home Assistant's handling of this is well-timed. I was just looking at the possibility of redoing my openHAB config in HA but this makes it really clear I don't want to go within a 150 mile radius of HA.
I've been using HA a lot in the past and written some components. But a while back they moved away from allowing pure YAML configurations and required some components to do setup via the GUI only. So it's not longer trivial to make a immutable deployment of HA since you will always need to manually make adjustments afterwards.
Hah! I guess they don't like the Nix approach on multiple levels :D.
I mean any package team who harasses people exercising rights they've explicitly granted is a bit concerning.
