No.  RFC 5819 [2]:

"For each selectable mailbox matching the list pattern and selection  
options, the server MUST return an untagged LIST response followed by  
an untagged STATUS response containing the information requested in  
the STATUS return option."

INBOX matches the list pattern (It is explicitly contained in the  
search list) and the selection options (which is empty), so the server  
MUST return both a LIST response -AND- a STATUS response.

2.1.10 changelog has this cryptic entry:
	- imap: Various fixes to listing mailboxes.

Maybe that is what fixed things (I don't see this behavior in 2.2.6).
