I am explicitly emailing you to let you know that gnome-shell-extension-no-annoyance will be removed from Debian Testing in a few days as part of the GNOME Shell 48 transition because of this bug. See the earlier email for more details: https://bugs.debian.org/1096057
It can stay in Testing or be returned to Testing if someone updates debian/control and metadata.json to mark it compatible with GNOME Shell 48. I didn't do that myself because I do not know how to trigger the "Window is ready" notification that this extension suppresses so I can't verify whether the extension works. (I'm also not a maintainer for the extension so I don't think it's my responsibility to fix this bug.) Note that packages that are not in Testing by April 15 will not be able to be included in Debian 13. https://release.debian.org/testing/freeze_policy.html Thank you, Jeremy Bícha
