Nothing on Hydra so far. I asked already - it mainly remains for you/devs to choose the right moment, and I can create it.

Say, now they'd probably want to add in recent master commits, as gnome branch is missing two weeks including a staging-next merge.

In reply to @donskifarrell:matrix.org
I've suddenly ran into an issue with my local build tho. My boot sequence gets stuck on [ ok ] Started Display Manager and doesn't load gdm.
This is using the most recent pull from github branch, yet I was successful in building and running it from a previous pull around 10th Oct.

actually if it builds fine for you it is probably how i am using it in my configuration- i have a member of inputs in my system flake.nix pointing to github:NixOS/nixpkgs/gnome, and then in my modules i've added:

{
  nixpkgs.overlays = [
    (self: super: {
      gnome = inp.gnomeNixpkgs.legacyPackages.x86_64-linux.gnome;
    })
  ];
}
