I take it that you’re volunteering?  :-)

The change is a simple one-liner, but making sure that nothing breaks of
course takes more time (mostly CPU time!).

<https://www.gnu.org/software/guix/manual/html_node/Installing-Debugging-Files.html>:

     The ‘debug’ output mechanism in Guix is implemented by the
  ‘gnu-build-system’ (*note Build Systems::).  Currently, it is
  opt-in—debugging information is available only for the packages with
  definitions explicitly declaring a ‘debug’ output.  This may be changed
  to opt-out in the future if our build farm servers can handle the load.
  To check whether a package has a ‘debug’ output, use ‘guix package
  --list-available’ (*note Invoking guix package::).

It’s mostly a matter of disk space and bandwidth.
