Well in windows we use to manually change the UI elements depending on the
scale factor. This approach means we would need to take everywhere the scaling
factor into account (for all the margins and whatever).
Compared to HiDPI scaling in GTK3, where this is all done in the lower levels
so there it looks mostly the same as without HiDPI scaling. We decided some
time ago that we would do the same for other backends or generally for VCL, but
nobody worked on it yet.
