Matter doesn't seem to be talked about much anymore. I would not be surprised if something else catches up and takes over before it gets big, like Bluetooth mesh or something.
Personally my ideal HA would just be if YoLink made their platform open source. Their hardware is cheap and actually works pretty much perfectly, the only thing missing is open local APIs.
I've been really pleased with YoLink though I wouldn't call them perfect. Over time I get occasional alerts for transient disconnects, and their UI robustness could be improved (like the Android app screens where I make changes but those don't seem to "stick" to the device until I redo it a few times).
