In 5.6 this “works” by disabling batching once generated values are involved - batching is disabled in order to access the generated values immediately after the insert/update. I just wanted that to be clear, if it was not.

In 6.2 there are some there are some bugs still being worked out with batching as we discussed on your other report.

FWIW, some version after 6.2 might offer the ability to combine generated values and batching, but that’s certain yet
