(Do you mean if the parser isn't fixed?)

Making changes to the HTML parser is very risky for browser vendors. Even  
seemingly innocent changes like e.g. not dropping whitespace before <head>  
[1] can break sites. Making blocks not close Ps is not only risky, it is  
pretty much guaranteed to break many sites.

As for new features; new features generally don't require much (or any)  
changes to the parser, and furthermore new features don't suffer from  
legacy content depending on a specific behavior.
