I am very opposed to this, they do different things.  Having abilities
isn't a bad thing and numerous Web sites and libraries make use of qsa, not
just because find was not available but because different APIs shapes
interesting new possibilities, different ways of looking at problems,
etc... We solve problems with the tools at hand, so given that it has been
widely implemented a long time, you can safely assume we have found good
uses for it.

There are a vast number of libraries and websites that have use cases for
find, this is especially true because selector engines that solved those
cases evolved in the wild a long time ago.... it probably would have been
nice to have had that native first, as it would have been a more immediate
help for the vast number of users, but qsa is definitely useful.
