It's what we mean when we say "majority of browser engines" but that has  
been misinterpreted purposefully in the past so I thought I would try  
something new. I guess I should not be surprised by your remark.

I created a variant of https://bitbucket.org/annevk/simpleserver that gave  
me more control over the HTTP section. Then I transmitted the following to  
a client:

Connection: close


I tried the same with the charset declaration missing and a couple of  
other variants.

It would only start breaking IE when people would actually start using it.

I did not say that. What I said is that it makes sense to change HTTP  
because double and single quotes can be used all over the Web Platform  
interchangeably. Often though more lenient syntax is more compatible and  
authors do not always test in IE. There are places where IE has negligible  
market share.
