We should do this. I'd argue that we don't want to do this now.

It *can* be done, but the `find` route provides an important service: canonicalisation of the URL prior to adding mappings. We can shift that responsibility to `BulkAdder`, but it's a can of worms. It's requiring effort on two parts of the tests (to remove some old ones, add some new ones, and change the way things work in order to retrieve mapping IDs), and I need to be done with this today. We lost a lot of time to mySQL and there's a hard deadline for CMA crawlers. And this works. Not in the purest way possible, admittedly.

I'd be relieved if we were prepared to take this on as mild tech debt, because I think the redirect is not our (you may read: 'my' :wink:) biggest problem at the moment.
