Concrete example: I frequently want to use the Jetbrains EAP IDEs. The EAP/Beta/RC are not in nixpkgs. Would there be interest of including this? This is fairly easy I think, but would require someone to make a PR each time a new version is released (I could volunteer to do make the PR and run the update script when new versions are released). (I currently use an overlay to have them available).
However, since I’m new to Nix/NixOS/Nixpkgs, I thought I’d ask before creating a PR (also apologies if this is not the right place for this question).
