not telling you what to do, but IMNSHO someone with time should look
into https://wiki.debian.org/DebianEdu/Status/Bookworm#Known_problems_that_need_to_be_fixed
else we don't have Debian Edu / Skolelinux in bookworm.
You are certainly right, from your point of view. But I lack the motivation to work on these tasks, even if I had time.
Besides, I think that these tasks are difficult for a beginner (who is not familiar with all the services and their configuration details).
Kind regards,
