[whatwg] Do we really need history.clearState()?

I should've responded to this more directly:

The History object is - quite purposefully - very limited in scope and abilities.  Today, it gives the ability to navigate back and forward a number of steps.  Period.  

The pushState() API adds a very limited way of adding new items programatically.  clearState() also adds the ability for a script to remove entries, but only ones that it added.  Period.

Same-origin policy be damned, I really don't like the idea of a script being able to remove items that it didn't add.

As I said in my previous reply, I think it might be useful to give a more fine-grained version of "clearState()", but that could always be added later if there's demand.  And I still think it should be limited to affecting the string of the Document object's entries.
