The great thing about Nix is how the provided packages remain malleable. You can usually quite easily make a small override to a provided package to make it build from a specific revision of the source you desire, or add a custom patch, and Nix will just build it all for you then & there. Then you can go and rebuild bits of the rest of the distribution that depend on that using your custom version. If you so want.
