Just watched the RV interview post miner conference. TLDR: Neither side is strongly opposed to the implementations suggested but disagree on timing. CSW had a temper tantrum and went home.
I don't think the official stress test has started yet. Still officially 10 hours to go or so... I think they are just testing and prep. Flooding in order to "prime" the difficulty?
OK, seemed like BCH was getting flooded but then it stopped when no blocks were mined. Interesting.
