We need to first put back CI (Travis is MIA) and add Ruby 3.x to the mix. Want to help? Maybe copy from https://github.com/mongoid/mongoid-grid_fs or https://github.com/mongoid/mongoid-locker?

Btw, there are many projects in the mongoid org that could use similar help :)
