Imo, there's no need for big philosophy about this. Application.HiDPI :=
Off; should be enough for runtime (no need to store this property in
lpr/lfm or whatever, just put it after Application.Initialize). In
Lazarus options there should be: Enable hiDPI designing (can be true by
default if you want), so app design is done in old way and new
properties does not influence current projects just like that.
Some of us do not plan to switch imediatelly to hiDPI features (Michael
already mentioned why is it so), so global on/off is really needed.
