Sounds like the CA is doing too much during taxi out. At our shop the FO does the checklist verbal 'fuel required xx, yy onboard' and the PA for FAs to be seated for takeoff. In fact, another change they just did was now the CA doesn't do the mini-brief on his own leg for takeoff. The FO does the mini-brief regardless of who is flying. Freeing up the CA during taxiout is a good thing.
