1PH dominated by like 4 pools (pretending to be 6) is a concern. 1PH with individual miners constructing blocks themselves, that doesn’t worry me.
Don’t make the mistake of thinking simple scale will protect a highly vulnerable structure.

There will always be 2-4 large pools. That's the nature of mining incentives. Bigger pool more likely to get reward. Pool too big, reward is too diluted. It's a self regulating system. Real proof of work, not some BS uPOW. I don't forsee pools being a problem or mining centralization being a problem in Bitcoins system.
Again, this is about whether or not pools are building the blocks or not. I didn’t say DATUM would make pools small. Your point is correct, but not relevant.
I wasn't suggesting they would make pools smaller. I generally agree that DATUM and STRATUMV2 are good developments, but what's the incentive for pools to begin using them? That's the key here. Miners, whether in a pool or not, respond to one incentive. Getting paid. I don't see adoption (of pool participants building blocks) happening at a faster pace no matter how much development funding happens. I'm all ears though. We want the same thing.
