I have a different point of view here. If HTML 4.0 doctypes wouldn't 
trigger quirks mode, authors were less likely to unintentionally use 
that mode (I know that this is happening, because I often work with 

My point of view is that we shouldn't trigger a mode, because the mode's 
there anyway. We should trigger it when it's necessary. And imho this 
isn't the case for HTML 4.0 doctypes.

IE 6 to 8 and Opera 9.5/9.6 currently trigger almost standards mode for 
HTML 4.0 doctypes. IE (8) will remain unchanged for a long time 
(depending on Win OS success 6 to 10 years).

Firefox and Safari could align their behavior in the next 2-3 years and 
update their users accordingly.
It's true that IE9 could also change, but that's not optimal in my 
opinion, because older IE versions are much more dominant (and much 
longer used) than older versions of other browsers.
