I find text visually less fatiguing at high-DPI even though I have no problem reading it on my 24" 1080p secondary monitor. I don't think it's a matter of productivity as much as comfort (though maybe comfort indirectly affects productivity).
I agree with everything you said about the more recent releases of MacOS. Maybe I was being too generous in my previous comment - it really does seem optimized for very small laptop displays, so that's probably why they have recently placed so much emphasis on fullscreening everything (and also why they got rid of the Expose grid - horizontal swipe works better on a laptop trackpad).
