Xamarin is officially in End Of Support. But Maui has definitely missed the mark. I was deep in it around net6/net7 timeframe, and net8 was supposed to be a big step forward, but they burned a lot of good will with the rollout. I saw a lot of hubris not only from the Maui side, but also from the .net ecosystem as a whole. Specifically whoever was pushing workloads. The pain points around that were huge sources of unnecessary friction, on top of the really buggy initial versions of Maui.
