Because sometimes (not always) it does matter. And when it does, close proximity is very important. Then you need to literally work side-by-side. Done it many times. Our local SW guy sold his horse ranch and moved out of California. Only to Reno which is under 2h drive but that's already a bit far.

There's plenty out there that should be directly adressable via MCU. For me it's probably going to be something from the PCM290x series but there's also SPI variants and so on.
