So?  The behavior change is pretty trivial.

Hasn't so far.

Which it still does.

If you parse an empty stream with the HTML5 parser, you get a DOM 
containing <html>, <head>, and <body> nodes.

So the only behavior changes are:

1)  There is no longer a doctype node in about:blank.
2)  There is no longer a <title> node in about:blank.
3)  If you do "save as" on about:blank you get an empty file instead
     of a file with a small HTML document in it.

Other than a knee-jerk "it's different", why not?
