That is exactly what I mean by backwards compatibility, you're introducing 
stricter requirements in later UA's meaning that authoring to the spec 
breaks compatibility in DOM 2 implementations (because the author can now 
_rely_ on a particular ordering, rather than having to use the simple code 
methods to create an ordering)

Without use cases for requiring an order, it shouldn't be done. It probably 
should've in 2, but wasn't presumably for reasons, what's changed about the 
reasons then?

Certainly, however I don't see anything else that does, so without that, 
there's no need.

You can in some current implementations, and there's nothing in any current 
specification that disallows this.
