the Home Assistant automations tend to stay working without major overhaul far longer than stuff I used in the past

This is a major selling point, and also why I haven't bought into any cloud-based home automation system (unlikely I ever could get past the surveillance aspect anyway). These systems are supposed to last as long as your home does, you don't want to replace/overhaul the system every few years because the supplier wants to earn more money from you.
