After "bzr join" you can keep updating the imported vendor branch code by running "bzr merge <vendor-branch-url>".
I'm not sure if 'bzr join' equals merge-into, afaik it's a bit more sophisticated at the cost requiring a newer format (I have no experience with merge-into, though).
if you use "bzr join --reference" you can't make changes to the vendor branch without these changes also going upstream automatically IIUC.
