Jens Alfke commented on COUCHDB-69:
-----------------------------------

Maybe this goes without saying, but this would be excellent for implementing wikis or other version-control systems.
It would also help in designing distributed systems where there is less mutual trust between instances -- pulling a new version of a document from a peer is less dangerous if the existing version persists and can be rolled back to.

> At the moment, compaction gets rid of all old revisions of a document. Also, replication also deals with the latest revision. It would be nice if it would be possible to specify a list of revisions to keep around that do not get compacted away and replicated.
