I recall some years ago seeing some lisp code that wanted to calculate 
the real dpi of the display, as opposed to what is reported by the 
system (which can be influenced by user settings for font size, or in 
some cases hardcoded to 72, 96 or other common values).

The change you are proposing would be incompatible with that way of 
using display-pixel-height.
