MAUI WinUI integration instead of separate "reference Project"

[Zumpel96]

I just finished the Getting started part of MAUI and I can execute the Android platform without any problems.
Anyways I stumbled across something, which looks, in my eyes, a little bit unnecessary.

When you create a new MAUI project (for example HelloMaui) and generate a new solution, you get two projects.
One for WinUI HelloMaui.WinUI and one for all the "other" platforms HelloMaui (Android, iOS, MacCatalyst).

However, why is there another project?

Within the WinUI project, you only have references to the "main" project and therefore, in a plain vanilla environment, just a 1:1 project, which only consists of references, without any differences.

I really do not understand, why this is done, since another subdirectory in Platforms called WinUI or simply just Windows would definitely be clear enough. I didn't mess around with VS2021 yet, but from experience I am trying to minimize the number of concurrently loaded projects to the performance issues of previous VS versions. It would also make the solution a lot more structured.
