So new context...

When mentioning decentralization, I have heard a clarification explaining that they were thinking about miner decentralization.

Still, I can't shake the feeling that you can't call a PR purely technical when it is a change that affects game theory. In this case the game theory as to whether a minority of miners will gain an advantage by capitalising on a private market that the overall network applies friction too otherwise.

This wasn't just a change from an int to a long, or the parallelisation of actions. This is a change that has external effects and that should affect whether you ack or nack.
