I'm not finding this documented here https://docs.couchdb.org/en/stable/api/document/common.html#db-doc
Can you point to the documentation for that?

Alright! I'll close this issue now and we'll re-open it when they are getting closer
thanks for writing in about this, pouchdb should definitely be able to support this when couchdb does!
