Is there some doubt that the ability to tag an arbitrary set of elements
and later easily get an array of those elements is a useful feature for
web development?

If you would like use cases, I present all of the web pages currently
using a JS implementation of getElementsByClassName based on
getElementsByTagName("*") and some manual class name inspection logic.
