I'm generally against using nixConfig as upstream Nix does not have a way to ignore it, and forces you to interact. Lix ignores it by default, but not everyone uses it.

The benefits would be minimal, as I don't think anyone runs hyprland with nix run from the flake that often.

Yes this is true,
Is not being able to ignore the sustituters hint an issue?

The benefits would be minimal, as I don't think anyone runs hyprland with nix run from the flake that often.

It would also hint for imperatively adding the keys to nix.conf permanently when you use hyprland as a flake input of a nixos system (and make sure users are aware of the cache)
