peer: remove non iterating batcher (API) The last use of this API was removed in b6e71f8af5b8 in 2016. While not formally deprecated, as of the last commit the code is no longer explicitly tested. I think the new API has existed long enough for people to transition to it. I also have plans to more formalize the peer API and removing batch() makes that work easier. I'm not convinced the current client-side API around batching is great. But it's the best we have at the moment. .. api:: remove peer.batch() Replace with peer.iterbatch().
