I've shared this in the past but probably better to do it here in the comments as well.

Software can go into "maintenance" mode. But people simply don't go into maintenance. Developers move on, and once they are gone they will not come back.
If we remove all sort of additional work and we don't allocate a minimum monthly amount to keep a part time team active on the project I don't think there will be a team around if somehow we decide to resume the development in the future.

That said, if this is the decision of the community it's totally fine.
