I believe the snap reaction here is "you haven't tried to diff XML, have you?
A text-based diff of XML sucks, but how about a DOM based (structural) diff?
Sure, but how much more processor horsepower is that going to take.
Scale is a driver in Mediawiki, for obvious reasons.
I suspect that diffs are relatively rare events in the day to day WMF processing, though non-trivial.
That said, and as much of a fan of some sort of conceptually object oriented page data approach... DOM? Really??
We're not trying to do 99% of what that does; we just need object / element contents, style and perhaps minimal other attributes, and order within a page.
