This should be awesome. :-) It often arises when one wants to reproduce a scientific paper providing the versions of the tools used. For example see [1]. Well, it is not easy [2]: locate in which .scm file the package is defined, then checkout the Guix repo and `git log` this file. And it is even more error-prone if the package has changed of .scm file (e.g., the recent haskell-xyz move).
