Roughly the same question can be (and was) asked for <!DOCTYPE html>. 
(It is supported by IE7, but not used in today's documents.) Ideally, I 
want IE to have one decent rendering mode for HTML5 and above, 
regardless of the mime type. If Microsoft supports such a mode before 
the significant bugs are fixed and without an opt-in, it'll be just 
another quirks mode and we need yet another doctype or mime-type switch.
