It is an absurd position that your way of thinking is logical while the counterparty’s is emotional. In fact quite dishonest as a rhetorical technique. Less of a notch that is asymmetrical would look worse due to human preference for symmetry, and what the parent said is that the current solution does in fact put the statusbar at notch level. So why does it matter?
I suggest looking at the response the user made to the comment for a different reaction than your comment. Also i didn't say one way was better nor that I looked at it logically, or did I?
Interesting! Good design is human in nature and may sometimes be against a colder logical approach. I do wonder about brand and identity though but those are harder to look at from a distance.
