The propagation time you're thinking of is from the pool to the miner, and even
now that is significant for pools that do not pay for stale shares. I remember
an Australian pool mentioning that problem on their website as a reason for the
pools existence.

I would expect selfish mining, as well as orphans becoming more important in
general, to centralize the physical location of hashing power too. If the 100ms
delay to your pool impacts profits you'll have an incentive to locate your
mining equipment physically closer to the pool. The next step is pools wanting
to physically locate themselves closer to other pools.

It would not be good if all Bitcoin mining was done in Iceland...

Not ignorant at all IMO.
