Cache for other GHC versions?

Is there something I can cachix use to speed up development with haskell.packages.ghc902?

I have had good luck with using the nixpkgs revisions listed for various versions of GHC on this page. Unfortunately, GHC 9.0.2 is not currently listed.

As GHC 9.0.2 has become the default recently, binary cache will be as good as it can be going forward. The change should be in channels soon (is already in nixos-unstable-small last time I checked).

I probably should have mentioned Iā€™m using a flake

Updating it to a more recent nixpkgs commit / the nixos-unstable-small branch would have the same effect.
