It's a decision for the developers of the language:

be concerned about progressive rendering -> use the painter's algorithm
be concerned about rendering speed -> don't use z-index
hope for *very* high bandwith -> parse all files (external CSSes etc)
before starting to render
hope for pretty fast machines -> feature z-index

Different combinations of the above make sense ;)
for example: 1+B, 2+A, A+B, 1+2(current state)
