Comment (by azaozz):

 Thinking more about this, a "middle point" between the two approaches
 would be to tweak `_wp_add_global_attributes()` so it can return just the
 array of `$global_attributes`. Then check the prefix against it. That way
 only hard-coded wildcard attributes will be allowed. (That would still
 require sanity checking/security auditing of all `aria-*` attributes if we
 decide to add them.)
