Ah, too bad.

Back to the drawing board then.

Implementing my idea in my environment using a cluster filesystem would
be a very big pain in the lower back, so I need a different idea to
share the shared folders with all nodes but still keeping the user
specific mailboxes fixed and local to a node.

The imapc backed namespace you mentioned sounds very interesting, but
this is not implemented right now for shared folders, is it?
