Shouldn't this be a method of CWVTranslationController instead, at the same
place as other translation policy methods?

I agree, we should move it, it is ok if it's a class method there.

Can we also expand on the comment here to specify what is cleared in relation to
the other API. For example, does this clear translation_policies set in
CWVTranslationController? It isn't currently clear.
