Yes exactly. I mean at least the first patch would just add the fields displaydpi+forcedpi to the Display struct and allow querying those. So it would be possible to have applications to deal with different DPIs.
From what I understand from the plan9port code, on macOS it makes a smart guess [1] if it's retina or not (=> displaydpi value). Also users can toggle CMD+R [2] and toggle that manually (=> forcedpi value).

True that's quite a pain. Maybe that's why it's such a mess on Linux.
