For what it's worth, we fixed a number of problems that the WHATWG  
standards process and other implementations flushed out, and found  
workarounds for the compat-issues in Apple-specific content. It was  
somewhat painful but I think it will lead to a better web than adding  
a new mode switch would have.

I think the CSS problems are somewhat different from the HTML ones;  
adding new elements, attributes and APIs is fairly unlikely to break  
existing content compared to fixing CSS layout standards compliance  
bugs (particularly bugs that have been around for many years).

Quirks mode is about bugs, not standards versions. And it sounds like  
a new quirks mode would also be about past bugs, not changes in the  
standards themselves. To opt in to or out of an old set of bugs, it  
sounds like the right thing is UA-specific versioning, not standards  
versioning. I don't think you would expect other UAs to emulate the  
locked-in IE set of quirks for every standard version in the future.
