New Control Panel stuff is C++/XAML/WinUI, definitely not web controls.

The big trouble with Windows' embedded webviews in the past has been that they only updated once or twice a decade with Windows updates, so tied to very specific IE versions and often meaning applications that used them were stuck in specific versions of the web platform. The new "WebView2" from Microsoft is powered by Chromium Edge so it should be a lot closer to Electron in practice (though still, updated at user/system pace [just now on the much faster Chromium Edge cycle rather than the slower Windows cycle], not developer pace which is often the specific draw to Electron).

The startup times and RAM usage most likely going to be terrible, most users don't have the luxury of the latest fastest laptop.

The WebView2 runtime is going to be shipping with Windows soon. I imagine an app using it will be about as resource-hungry as a browser tab.
