Sorry for my late reply!  And yes, the payloads in Vector APIs are always be flattened for current vector size. What my concern is the larger vector size like in Arm SVE after we support the SPECIES_MAX vectors, and the expected behavior/difference if people set a smaller max flat size with `InlineFieldMaxFlatSize`.

Thanks,
