A1-0 Low Hanging Fruit

Yes, but the two are related. Reading Maverick’s post, his opinion on that matter is that,

I don’t think it’s all that unlikely that if the plot sizes are increased, the limit on megastructures would also be removed, or at least greatly increased. We shouldn’t be viewing them as completely separate matters, because we need to think of the broader impacts of the proposal before we decide to make such big changes to the canon.

While yes, I agree that this could be true, I think it’s more of a matter of whether it is true. That question is best left to the people who have actively chosen to create nations with lower tech levels, rather than us.
