If the two of them have met the criteria then good on them. It is rather acenine to criticise people you have no first hand experience of, apart from being rude. However, it would be different matter if the average age of command were to fall especially if it were due to recruitment need.
We have seen this in medicine: older consultants retiring, significant shortages and trainees being made up with the absolute minimum training. Patients and safety have suffered.
I do hope there are no lessons to be learned here.....
