UWP is fine and in fact should be preferred for apps targeted at content consumption. E.g. you want your IM, Facebook app, media player, all the video games to be UWP so that you would know the companies making these apps are not stealing your data and not making your system too vulnerable to RCE attacks.

This also applies for any professional apps that do not require extensive access to the file system.

For the rest of the stuff like system tools, arbitrary file editors, user interface utilities you need to run in full trust UWP is currently not suitable.

Usually they can be restricted to specific folders, e.g. music, video, photos.

Those should be web apps.

Only a few of them can be web apps. Web is too restricted.
