Two originally identical things may be different after you change one of
them. Yes, that's trivially true, regardless of what triggers the change
(you can just use removeChild instead of document.write if you like). So
if this is supposed to explain

then you really argue that <script> execution should be delayed until
after the document has been fully transformed into a tree. As you do
not seem to argue that, your argument doesn't make sense. Further, you
just claim "we really need" this. We do not. And we do not have that
in many cases either. What you say is nothing but nonsense.

That is obviously incorrect, already for the fact that scripts other
than those inside <script> will have control passed to them before any
'load' event occurs, a trivial example being 

  <img onerror='...removeChild(this)' ... />

document.write is also not a property of XHTML, but of the HTML 4.01
and XHTML 1.0 Document Object Model, and yes, it does have the write
method for XHTML.
