Ideally, whole OS display layer should be independent on physical resolution of the display. That is not an easy thing to patch into OSes that were using pretty similar PPI for last 20 years, especially in legacy applications. That said, Android can do it, Apple did it (though the way they implemented non-integer scaling is costing them a lot of performance [1]) and interestingly enough, web pages can do that too. Linux display system is going through a bit of rebirth after decades of X and should be able of resolution independence as well. So it looks the times ahead will be better.
