Just my 2 cents as a not-pd-dev (sorry).
Given that PD is mostly conceived as a real-time enviroment, and all the non ASIO and most of all MME, MMIO stuff on Windows is pretty distant from the real life concept of real time due to latencies that mostly need to stay at minimum average of 10ms on the average Win based systems, i'd take away all the "useless" stuffas indeed all the MMIO drivers.
WASAPI is the modern standard for Windows systems and btw it's still not on par with ASIO.
In their recent versions it seems that Jack (and its Jackrouter ASIO "skin") and PortAudio are pretty stable on Windows.
