I think this is reasonable.

@nico mentioned that he found the other PR a bit surprising though. It's not obvious which features that should be gated on the driver mode or target flag, but we do enable MS compatibility extensions based on the windows-msvc target, and I think it makes sense to include the aliasing and volatile behavior along those lines.
