Ask Apple why not. :)

There is no standard for how IMAP clients are supposed to save draft 
messages. Because of that, every client does their own thing and fails 
to document it or make the slightest effort towards interoperability. If 
a draft message is anything other than plain text, you should treat it 
as a document of a special type accessible only to the program which 
created it. Because it is.

You can always see what MM has as a raw message with the View->Show Raw 
Message menu option, and while it's not exactly "user friendly" it is 
not hard to figure out whether a message really has any attachments. If 
it does, the first "Content-Type" header will be either multipart/mixed 
or multipart/alternative, and there will be sections of the message that 
have their own set of MIME headers followed by a block of base64 text 
(fixed-length lines, no spaces, all ASCII characters) for any parts that 
are binary files.
