The latter would be a much larger and likely breaking change for the web. One could certainly argue that it's disruptive to change z-ordering as a result of rounding a corner but we do that for opacity for reasons that are not so explicable to authors.

On the flip side, we don't do it for overflow, which is very counter-intuitive (and adds greatly to implementation complexity).
