Most things I've seen working in this space are attempting to minimize
the data transfered. At least for the miner-interested case the round
complexity is much more important because a single RTT is enough to
basically send the whole block on a lot of very relevant paths.
I know much better is possible (see up-thread where I linked to an old
proposal to use forward error correction to transfer with low data
transfer (but not optimal) and negligible probability of needing a
round-trip, with a tradeoff for more overhead for lower roundtrip
