@ajs6f @barmintor @awoods @escowles ? Anyone want to offer a defense for any of these commits?

You mean a defense for the stuff you're killing? No, I'll happily hold your coat while you punch it to death, and I'll pour you a beer afterwards. If the tests pass and the surface of our API remains substantially the same, then these methods should have been long gone. I am a little weirded about POST-for-DELETE, but then, batch delete actions across RESTful HTTP always end up looking a bit weird, because

9.7 DELETE
The DELETE method requests that the origin server delete the resource identified by the Request-URI.
