Hi,
I followed HA since the early days. There always have been ups and downs. We gained huge improvements and huge features. This always comes at a cost of stability. This has been taken care of just wonderfully too.
However these days I think we should look more on stability again. Me and my friend have seen 100% CPU load by a bad (user configured!) automation, or a ESPHome stuck in reconnecting. This might be coincide. It might be not.
I wish for more self awareness of HA to improve stability. Maybe even some self healing. I wish I could help for that.
