Currently that means the second p child of div, if it has the class 'foo'. How would you get that behavior with your proposal?

div > p:nth-of-type(2).foo {} be different from:
div > p.foo:nth-of-type(2) {} is a possibility but order has historically not been significant within a simple selector and adding that now could be problematic.

It would likely be better to simply add p:nth-of-class(foo, 2) or something like :nth-of(p.foo.bar:visited, 2)
