I'm asking because there are pull/merge requests for four compositor implementations (wlroots, KD) of the updated ext-idle-notify protocol that are about ready to go, and the main thing holding up those requests from being merged is that wayland-protocols 1.40 isn't out yet.
I did notice that there was an unmerged MR to update the docs for linux-dmabuf (https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/376), and since there's another merged MR also with updates for linux-dmabuf (https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/364), it crossed my mind that the plan might be for both those MRs to be merged before the next wayland-protocols release. However, that's only a guess on my part. (Please ignore an earlier post sent under the wrong email address!)
