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).

Well the access to the information will ease the time travel. :-)


Thank you for this initiative even if I am not sure to clearly
understand yet what the Guix Data Service is. :-)


All the best,
