I agree with David, and Debian.  The fact that they include "-r2704" in
their tarball name suggests that they might release a newer version
called "2.82-r2705", and I want Guix to be able to answer the question
"which version is newer?".  If 2.82-r2705 fixes a problem, I want to be
able to see if the version I have installed still has that problem.
Does that make sense?
