Question about interface of low_latency_dispatch

I'm a bit confused about the low_latency_dispatch interface. Why doesn't the interface **support passing topk_weights**? If the dispatch interface cannot return topk_weights, then it is necessary to
1. recalculate based on the obtained hidden stats
2. or use the dispatch interface again to transmit and obtain topk_weights.
However, based on our actual tests, the transmission time for all_gather during the decode stage is very short, so adding recalculations or additional transmissions does not offer any advantage. Or is it related to your experts' interface?
