Ai, yes, you're right. To make map_batches
more safer, we added an is_elementwise
parameter in #13181, which defaults to false. If you set it to true manully, It fallback to this unsafe behavior as the document said(the trade-off is that it won't run in the streaming engine any more).
Of course, this document definitely needs to be updated.
