I think experiments in living are to be encouraged. We pay lip service to the idea that a 'one size fits all' arrangement is absurd, only to end up with the idea that three or four options will cover all the nuances.
Separate rooms, certainly. In the past nigh on 13 years, Mrs Hopper and I have slept in the same bed/room maybe six times. It's weird at first, but now I wouldn't want to share with anyone.
