I agree with the general aim here. Would appreciate input from Michael in particular on these + ideally others!

The use cases for this driver don't comply with the current ABI. The ad7746 and ad7152 need an external capacitance or voltage reference to automatically calibrate themselves which is not the normal use case of the calibscale and calibbias ABIs, a new ABI was needed.
