Very.

Maildir specifically uses .folder.folder names so that the IMAP server 
can find _all_ the folders by reading a single top-level directory.  If 
sub-folders were stored ../folder/folder, then the IMAP server would 
have to scan the entire mail directory (in my case, several gigabytes) 
every time it started up, so it could find the list of folders.
