Hi, If we want this in an initial minimalistic xdg_shell version, this needs to be targetted at xdg_shell unstable v6, which currently lives on a branch and as set of proposed patches. We cannot add this to version 5 anyhow.
If we indeed want this in the core protocol now, and not in some extension, then I'd suggest rebasing it on top of "xdg-shell: Turn xdg_surface into a generic base interface" [0] and adding this request to the xdg_toplevel interface. I'm in the process of sending a updated version of that series, but in general, up to that patch, it should be more or less the same.
