It is in a technicality But the reality is, it will always move at the pace and at the whims microsoft wants it to.
Thats not necessarily a bad thing honestly. But you can really get i to trouble making it a core dependency for something like a game engine. Unity’s users didn’t care that Microsoft hadn’t posted the runtime to iOS, they expected their games to run on iOS. So Unity did a bunch of dev work that is now kind of a bad investment with .NET 8. This is the core of why they wanted to charge an install fee in the first place.
