How will this dependency data be kept in sync with the go.mod file? If someone submits a change that updates the version of any of these packages (which I have done more than once) do they also have to update this file or is file somehow automatically kept in sync with the go.mod file for the project?

This has to be updated together with the command
nix develop --command gomod2nix.

If adding flake is OK, I'll try to add workflow that generates automatic PR when dependancy changes.
