Well even if the software is functional, the underlying OS doesn’t support it in ways that are important. Like suspend and resuming games. Then when Windows can have a random update, the extra software may break or run into serious problems until the devs can get an update up for it as fast as they can on reaction. Nvidia STILL commonly runs into these problems with just Gpu updates. Things always break and they gotta have multiple versions of stability going and staying on top of updates for the latest games.
In other words, nobody has a problem with Windows until Windows suddenly spawns one for them to have for seemingly no reason and at the worst times. The more Beta the software is, the more commonly this happens.
I do gotta say those controllers may finally be a replacement for Joycon on PC. They look great!
