@yvan-sraka sorry if I missed the discussion somewhere, in this approach do we move nix-fast-build to some other level, or do we just not need it any more

We use nix-fast-build when we run nix develop (as it's nice to quickly have a working developer environment). However, in CI, it's better, IMHO, to have jobs run sequentially, particularly when you want to reproduce an issue in CI (if your build fails in multiple places, it's impractical to assert that you fixed one issue if they occur out of order). WDYT?

But it's indeed different if the runner is not ephemeral and has some persistent /nix/store. In that case, nix-fast-build has some value since it avoids some redownloading (it partially caches even failed builds). It might make sense to reintroduce it when we have the new runners :)
