Teams is thankfully now using WebView2 (less resource heavy), new Outlook is a PWA.
However I do agree with the gist of your comment, it appears everyone from the GUI civil wars that doesn't want to stay until the end has jumped ship to "Azure OS", or the competition (Amazon/Google), and most UIs are Web based or the classical Win32 ones.
Naturally "Azure OS" applications use the Web as UI.
Only WinDev themselves seem head down on using WinUI, and still don't grasp the competition, not only the WebView2 based stuff into their turf, the other OSes that don't require dealing with COM and C++ for basic stuff like OS widgets.
