I include this when considering buying something integrated.
For example Philips Hue is overpriced, but their Home Assistant integration is top tier and ultra-reliable. Contrast that with myQ garage door openers (LiftMaster, Chamberlain and Craftsman) recently breaking Home Assistant support on purpose, to essentially replace it with nothing, and they're dead to me.
So Xiaomi adding support, assuming it is reliable, definitely moves them into a better category.
