> In a gaming-only setup, Windows requires virtually no maintenance.
This is not remotely true anymore with Windows updates automatically restarting computers, windows updates pushing breaking changes especially in regards to GPU drivers, and more anticheats requiring secure boot.
These points are not (all) technically correct; for example, Windows does not restart "automatically" - it gives multiple options (this is important for dual booting).
Besides that, the root discussion is having a dual boot vs a virtualized windows; maintenance applies the same to both, it doesn't disappear when virtualizing Windows - the different is (the value one places) to context switching.
