Wouldn't it be possible to assume that by default, the user will be placed between both microphones? It would be less than ideal but just keeping the sound that hits both mics at the same time could be a nice default improvement.

That is actually the default with the webrtc beamformer (the sample recordings point straight forwards which effectively works out to being between the two microphones).

Yes this is the default. The beamformer is steerable and you'll notice that a significant portion of the code is responsible for steering.
