This is an important point: in a lot of ways, SMRs are a strictly worse than 1000MW plant. The potential financial benefits come from all the other factors you mentioned. I would rather have a "worse" nuclear power plant that actually gets built.
The hope of SMR is that it can be cost-effective at the same level that other factory-produced power sources are. If that's not on the table, then large-scale nuclear deployment mostly isn't going to happen.
Why? It then proves nuclear is uneconomical?
Regulatory arbitration like this serves nothing?
Don't get me wrong, I would love to see more nuclear, but bad nuclear is not in fact better than none.
