MSFT and their priorities. smh. Maybe fix the wallpaper bugs first when swiping between desktops before introducing more bug-riddled features that will never get fixed. Calling it now. There will be a memory leak with live wallpapers.
Wallpaper engine and similar apps won't be needed soon, as Microsoft has decided to reintroduce the ability to use video as the desktop background in Windows 11. The feature was abandoned long ago and was last available in Windows Vista.
