Are they experimental? I suppose this is a valid use case, right? I am in
favor of adding a warning, but I don't know if I would call them
experimental.

I suppose a repeated-batch use case may do this repeatedly (though then
users would need to recover the latest offsets for each partition, which I
guess is not possible at the moment?)
