It would be nice, but unfortunately X11 has the global co-ordinate space very deeply baked in to its entire API. There's no good way to do this. I think the only solution will be to work out a way for apps to declare that they are indeed HiDPI-aware and have scaled appropriately (e.g. _NET_WM_SCALE_FACTOR == 2), have the server watch those, and pass that through to the host compositor as appropriate, and make sure that whatever's rendering decorations accounts for this. Except then you run into the very difficult question of window placement: you'd need to offset all transients by the appropriate amount as well. So, if you have a window which you're scaling up by 2x, and it wants to create a transient at an offset of (40,40) relative to the primary, you need to shift that to (80,80) accordingly. The window manager would also need to enforce this wrt window configuration: if you have a 3200x1800 output, it needs to clamp maximisation to 1600x900, and so on, and so forth.
