I don't think your argument in favour of folders (mailboxes) is valid. 
An IMAP server don't need to treat $Junk/$NotJunk any specially, it just 
needs to be able to store arbitrary IMAP keywords. Most servers already do.
A recent Thunderbird can also be configured to set arbitrary IMAP 
keywords. (It also recognized $Junk/$NonJunk natively, but this is 
besides my point).
