We are coming to a point where doctype sniffing and the modes have  
almost nothing to do with HTML itself[1] and almost everything to do  
with CSS. (WebKit and Opera show that the modes don't really need to  
have much (anything?) to do with the DOM APIs, either.)

Furthermore, CSS has not needed new modes (or 'versions') in browsers  
that don't have "MSIE" in their User-Agent string[2] after the CSS WG  
started being very serious about the two interoperable implementations  
requirement (as opposed to pushing CSS2 to REC years ahead of  
implementation experience in the context of existing Web content).

launched triggering just about every UA sniffer *except* the scripts  
that look for "MSIE"
