Even on single monitor setups Wayland handles HiDPI and fractional scaling better in most circumstances, with the exception being apps that don’t support Wayland and are drawn at upscale 1x (mostly just Electron apps where the dev couldn’t be arsed to update their wrapper for some reason). HiDPI isn’t that niche of a thing anymore, having become common on upper midrange and up laptops. If only for that reason moving to Wayland makes sense. Aside from that, with X11 it wasn’t that uncommon to see cases where the layers briefly became distinguishable with things like white flashes other drawing anomalies which made for a less polished sort of hacky feel. That mostly went away when switching off compositing, but most users aren’t going to be doing that.
