This is actually false. For example, getElementById("foo:bar") is just
querySelector("#foo\\:bar"), which is ... nonobvious.
It gets worse if you don't control the id that's passed in, because
getElementById(arg) becomes querySelector("#"+cssEscape(arg)) where
cssEscape is a not entirely trivial-to-write function, if you want it to
work reliably.
