If you have the bandwidth to contribute I'm sure the people working on the camera app (https://git.sr.ht/~martijnbraam/megapixels) would love any assistance you could give them on postprocessing the RAWs.
From my limited experience with it, there's a huge amount of focus lag on the sensor itself, massive shutter lag, and then several seconds of postprocessing lag. I'm sure the last two can be improved in software, although the phone's CPU is so slow I wouldn't expect anything remotely in the realm of Google's GCam computational photography magic.
