There are pros and cons to the argument and while I think it might be a decent move now, later it might not be so great. Remember that eventually the pool will be about 6 million a year instead of 26,000,000 like it is now and that 10%ish might be an important component to make sure there are witnesses. I do think blocks should be spread further through the top, but keep the consensus with the lion's share of it still.
