That's funny.  I had figured that deliver 1.1 didn't fully support 
namespaces since I couldn't get it to work.  Silly me.

On our setup, postfix pipes to "deliver -d ${user}@${nexthop} -n -m 
${extension}" and this works as expected so long as the mailbox is in the 
private namespace.  If we try user+shared.test at domain, deliver logs "save 
failed to shared.test: Mailbox doesn't exist: test" and "saved mail to 
INBOX".  Is there something that should be changed with the config below 
to get deliver to deliver to other namespaces?

As for the original question about 1.0 > 1.1 transition for configs with 
non-empty prefixes for their inbox namespaces:  Why not have deliver 
prepend the prefix of the inbox namespace to the extension when the 
extension does not contain any separator characters?

This would preserve the old 1.0 behavior without changing anything when 
the namespace is specified as part of the extension.

Here's my dovecot -n output:
