Are you actually optimistic?
Not particularly. When I posted the request for comment to HN it got crickets [1].
Not enough people care about this. And the "safe" option has kind of shifted with the other index providers having moved first. That said, there were a lot of proposals and I'm not expecting all of them to be adopted.
Most indices will be buying proportionate to float, which is probably the correct thing to do. Only the Nasdaq 100 isn't float-weighted, and there's just less money in that index than the S&P500 (even with outsized weighting, Nasdaq 100 indexers will buy about 0.5% as much SpaceX as S&P500 indexers).
B: but what about your emotions
Very glad to see HN stereotype being upended :)
That's a request for an opinion, not an emotion.
