  > I'm pointing out that I'm in general against any risky changes on X11. If users want to use this features: Wayland is there. KWin is feature frozen on X11 and I highly suggest to the Plasma community to decide the same at the sprint. We will have less maintenance issues due to it.
  
  Yes, but many can't or don't want to use Wayland.
  In fact, the machine where I tried this on last had to use the proprietary nvidia driver to work properly. The wayland session doesn't work, it just freezes (I'll try to have a look at that though).
  
  If I'm not mistaken scaling is currently broken on Wayland due to use of XCB as Qt's default platform.
  
  > I can promise you that this feature will create bug reports, it comes with a cost to add this on X11. While we have a almost finished Wayland solution which is hold back by among other developers still working on X11.
  
  Sure, but by setting the same scale on each screen you get the exact same behaviour as with the current state. I'd say that's as low risk as it can possibly be.
