That's not even scratching the surface. They're spread far and wide and the ice is cracking. WPF -> UWP -> WinUI 2 -> WinUI 3 is an even bigger mess that's creating a system of frameworks that completely overlaps in functionality with MAUI, except it's Windows only - but not really.

The entire pipeline there doesn't even make any sort of coherent sense. WPF was clean, had extensive interest and support, and could have been trivially extended with more refined and "modern" styling/functionality. That's fundamentally all that UWP/WinUI are anyhow. But with each branching off, they splintered and annoyed developers in the XAML domain, to say nothing of the fact that I'm just pretending MAUI/Xamarin doesn't exist here.

I feel that the constant desire to push onto new things is, somewhat ironically, really holding back major progress. Because you put out some new awesome and really exciting tech, but things take time to mature. C# is absolutely awesome now, but was a mediocre java clone when it first emerged. It took decades of incremental and focused progress to get there.
