Suppose to but still not perfect. The communication with the china and there great firewall make propagation a big problem for big miner.
I was in scaling montreal and I did try to learn more about network problem with Matt Corallo and Rusty Russell and the network problem seems to be the place we should focus before working on bigger block size. A big farm ceo even said he created a node system to be sure to reach more node quickly to eliminate orphan.
This is another pressure to centrlisation (they will own the production and consensus infrastructure). The issue is not to propagate faster since any solutions there will just cause them to co-locate further to reduce propagation times - don't forget that it is relative (to other miners) propagation they are interested in; not absolute times. UDP vastly improves propagation (also improves anonymity and almost completely mitigates DDOS threats) but unless you can convince internet services to open up their UDP multicast routes, only huge farms with their own infrastructure will benefit - and benefit hugely at the expense of pools who will be wiped out! All these roads lead to colo datacenters and web wallets!
But I totally agree that bigger block sizes is a distraction. Then again. I think most people now realise it was always political argument rather than a technical one.
