Thanks, applied in git (only for experimental for now, but the version
in experimental will need to go to unstable soon anyway).

For the documentation, I wonder whether it might be better to pass
-Nlibgtk-4-doc to debhelper on non-Linux, so that the Arch: all
documentation package is complete (includes the gdk-wayland documentation)
on all the architectures where it's built, but is skipped entirely on
non-Linux (d/rules will automatically disable the documentation if it isn't
going to be packaged). That would avoid needing dh-exec.
