The question should be the other way around: Why is there `getElementsByClassName` when you can do `querySelectorAll('.myClass')`? Why have `getElementById` when we have `querySelectorAll('#myId')`? Why have `getElementsByTagName` when we have `querySelectorAll('tagName')`?

Apart from the historical reasons both `getElementsByClassName` and especially `getElementById` are optimised - the latter being a simple lookup - which I'm not sure `querySelectorAll` is able to take advantage of.

You’d pay the cost of parsing every time, but otherwise I’d expect SelectorAll to directly depend on getElementBy.. as relevant
