Cool!

Just out of curiosity: Weimar? Hangzhou?

We certainly appreciate help. However, implementing distributed deletion
is not easy - if possible at all. It's somewhat similar to wanting to
delete contents from the Internet.

Monotonic in the sense that you can only ever add information, not
delete. That's by design and not a missing feature.

Dropping a file is equivalent to writing a new revision with a manifest
that doesn't list the file. However, its history is preserved, its data
still available. Similarly, suspending a branch only adds a cert that
marks the branch suspended. Nothing is actually getting deleted.

You can of course always control your local database and even delete it
entirely. Or delete portions of it with mtn local.
