I'll also point out that miners with the goal of finding more blocks
than their competition - a viable long-term strategy to increase market
share and/or a short-term strategy to get more transaction fees -
actually have a perverse incentive(1) to ensure their blocks do *not*
get to more than ~30% of the hashing power. The main thing holding them
back from doing that is that the inflation subsidy is still quite high -
better to get the reward now than try to push your competition out of
business.

It's plausible that with a limited blocksize there won't be an
opportunity to delay propagation by broadcasting larger blocks - if
blocks propagate in a matter of seconds worst case there's no
opportunity for gaming the system. But it does strongly show that we
must build systems where that worst case propagation time in all
circumstances is very short relative to the block interval.
