N3xx calibrator for Power Ref API

Hi,
Does anyone know why the N300/N310/N320/N321 do not support the power ref
API? It seems that the calibration process simply stores a lookup table on
the host so I don't understand why this product line would be excluded. It
also seems that a small addition of an N3xx calibrator class (20-30 lines
of code) to usrp_calibrator.py would solve the issue.
