Problem here was that layer_collection_objects_sync wasn't called when the holdout property is updated due to frame change, so the changed visibility flag was never applied to ob->base_flag. Turns out there's no real reason to handle the per-object holdout property through the layer system. So, instead of merging both the layer holdout and object holdout into base_flag and checking that from the render engines, only handle the layer holdout (which can't be animated, so no issue here) through base_flag and explicitly also check the object holdout in the render engines.
