On #guix, 'smithras' pointed out that the issues.guix.gnu.org bugtracker front-end does not display re-opened unarchived bugs as expected:
http://logs.guix.gnu.org/guix/2020-12-01.log#193652 For example, <https://bugs.gnu.org/22952> was recently unarchived and re-opened after several years. However, the corresponding page <https://issues.guix.gnu.org/22952> does not display any of the recent messages, although it does properly describe the bug as "open".
