That's not really addressing the core of my point. Sure, you personally can choose to be conservative and not adopt something promising the world based on "libre". And you probably shouldn't unless you want to tinker. But if it becomes common and shows to be more flexible and reliable, perhaps you will change your view.

I too critically rely on heating. As system complexity increases with things like outside temperature sensors, I would much rather have visibility into their workings than not. In the middle of the night, that could be the difference between a quick ten minute diagnose and override, or waiting some hours for an emergency service call.
