> For all the folks confused why I'm saying you don't want a 27" 4k monitor for text, it's because the PPI isn't nicely sized for 1x or 2x, which means you have to set it to scaling that rounds and blurs subpixels.

This appears to be either a misunderstanding or a description of a deficiency in your environment for example Apple devices. For text there are 2 factors that control its size the designated size in points and for apps not sophisticated enough to scale elements appropriately according to DPI a scaling factor.

You appear to be suggesting that if you only had one knob you would be stuck with text that was either too small or too big however one or an application can adjust the size of the text independent of an integer scaling factor to produce a desirable end result. The same thing is true of images which are already trivially displayed at a different absolute sizes like every image on your browser ever.

For example on Linux most apps you are liable to run that aren't simplistic text apps are liable to be either QT or GTK. QT apps intelligently scale, GTK apps rely on a scaling factor one can set for example with an environmental variable. In both cases there is a setting for font size that effects 90% of apps of that stripe the minority having their own configuration.

It is incredibly trivial to have an environment that looks nice at any size.
