I simply believe in general, you can’t say “it is already much more pleasant,” but rather “I find it much more pleasant.” It’s a matter of taste, like, for example, an open vs. a closed kitchen. There are strong arguments for both forms here as well, yet in new buildings today, both certainly occur about equally often; at least you often see both, maybe even the open kitchen more frequently today. Here too, the question is which priorities you set: odor not throughout the whole house vs. communication while cooking.
It’s the same with the stairs. Privacy vs. always having to go through the cluttered hallway. The living-dining room is generally the space for everyone; privacy is found in the bedrooms. I don’t see a great necessity to get completely privately from the front door to the bedroom. Our children’s friends have to be okay with just briefly saying hello to us :p.
I already said this again and again here in the thread about a year ago, that there are simply different views on certain topics and that’s totally fine. Much less privacy for me, by the way, would be: the bathtub in the bedroom, and you do see that occasionally ;).
