Sure but different target market.

CRUD apps are non-trivial.

If Unity were to ship platform native replacement for WPF equivalent (hell or even winforms) it would become a really enticing app development platform.

Aren't these pretty much the most trivial UI apps possible? E.g. compared to other native apps like Photoshop, Blender, Visual Studio or Office, CRUD is mostly just about banging together custom UI frontend for a database.

Unity's editor is implemented in its own (old) UI system, same with Godot, so in both engines it's possible to create 'traditional' non-game UI applications.
