No, it hasn't. It has always been, as the label would suggest, to provide higher resolution imagery, which means sharper text, less aliased graphics. Extra room is a byproduct of software interfaces not being ready for high DPI displays, and thus scaling down when they shouldn't.

No, it shouldn't, and you don't need a larger monitor. I'm not sure why you would think this, but the whole point of having display scaling is so that the software can adapt to the hardware, as it should be. Pretty much every other professional application can do this, and Resolve should too, it's that simple.

Again, I'm not sure what you're basing this recommendation on. I have used 28" UHD monitors without any issue in any app except Resolve. They have a higher PPI and you get a more crisp interface and text and graphics (which, to reiterate, is the exact point of having a higher resolution display).
