I was going to say, the point is hidden ability catching in case it was needed for a request. ;)
Obviously I haven't missed not having it. It's just a rare missing Kanto entry I overlooked. I have a few others to fill in, and I realized after evolving Kingdra that it's actually an import, so I have to use a new one for the Kanto entry. Mew meanwhile is a different story; it's not in Gen. VI itself yet.
