Priorities.
The cabin crew announcement only crept in a couple of years ago. Personally I don't think it's that important in the grand scheme of things so can wait.
Also as for establishing comms between crew, what do you do if you don't get it? Stay s&l and resolve? The answer is obvious to us, but may not be to some (cultures).
The new method is unambiguous. Clear memory items, get the aircraft going down then sort out the other stuff.
By the way, you didn't mention the new lack of altitude restriction on extending the landing gear.....
