Please do see about approaching upstream about this in the context of GTK4 in a constructive friendly manner, perhaps from the angle of how to transition any distribution to a GTK that does not include X11 support with less migrational pain - this should be of interest for more cases than Gentoo. Maybe the idea about selecting backend stubs to include for their API functions, which would just end up returning what a fully enabled backend would return when the running environment is NOT that backend (e.g. when gdk-x11 functions are called in a wayland native app or gdk- wayland functions are called when X11 or Xwayland is in use). If that gains some traction, maybe we could also do this for GTK3 as well. Given how we'd have to end up maintaining this long term, such upstream discussions are sort of a soft blocker for proceeding with the patchset, as far as I'm concerned. Mart
