All this hustle to accommodate users decomissioning a list and after three days wanting it back... :-/
I'm curious how often you (or anybody) sees this request.
FWIW there are 3 issues related to per-list backups. It's a plausible feature (lots of potential applications), so I just added the below to Mailman's 2026 GSoC page, so maybe we'll get an intern to do it.
== Per-list backup == In Mailman 2, the list configurations were stored in list-specific structures as Python ''pickles''. Backup of a single list was just a matter of copying the pickle file. Currently there is no way to extract and restore the configuration and membership of a single list from a Mailman 3 installation. This project would involve picking a format such as a Python pickle or a JSON object, extracting the list-specific data from the backing database, and storing it to a file, as well as reversing the process.
