For emulators that intend to run games at full speed, the sorts of shortcuts and tricks needed to achieve high level emulation (which can sometimes fall short of emulation in a strict sense) are often incompatible with writing a plugin or extension to an emulation framework that focuses on accuracy.

In the case of the Switch, it's not necessary to emulate the whole device or even processor, especially if the intention is to run Switch games on a computer. Rather, high level emulation is more than sufficient — anticipate what the software depends on the actual hardware to do and redirect it to do the same using what the computer has available.

Switch has an ARM processor so it's definitely a requirement to emulate that, which QEMU is well-suited for. But to your point, Windows has great graphics APIs that would make it easier to pipe the graphic stack from the Switch OS into rather than writing your own implementation. The processor can be taken care of via JIT as well, but it still needs to be lifted.
