A good sign is that Microsoft IS using WinUI (WinApps SDK) to build consumer-facing apps. One of them is the Photo App Microsoft rolls out Windows App SDK-Powered Photos app for Insiders[^] If I recall well, another WinUI app by Microsoft was something to do with a "Phone" app, but can't quite recall what it was. While I can agree with some of the sentiment expressed, I am starting to see great energy on WinUI team, open-sourcing of WinUI was great and their OSS participation has been great.
