(guix gnu-maintenance) uses https://nongnu.freemirror.org/nongnu, 
whereas (guix download) uses http://nongnu.freemirror.org/nongnu/. This 
discrepancy causes my fix for <https://issues.guix.gnu.org/57477> to 
fail for the savannah updater. Can I just switch http -> https, or is 
there a reason for using http instead of https here?

Greetings,
Maxime.
