I think something like this was planned to be done some day with  
LISTEXT extension. Something like:

1 LIST "" * (STATUS)

Although I don't know how much it will help compared to just sending  
the STATUS commands all at once. Although that requires knowing the  
mailbox list, while the above command would get them both with one  
command.

These could anyway be standard untagged STATUS replies.

Another thing that I was planning was to send updated STATUS replies  
automatically to client without it even asking them. That would  
probably have to be optional and could be enabled either with config  
file option or with some new IMAP extension.
