@MrStevenStiffler this is exactly right. You can think of nested bonding curves as having a “composed curvature” that is a functional composition of the two constituent bonding curves. By swapping the curvatures in this case, the composed curvature is unaffected.
Note that not all nested bonding curve designs compose in this way. For example in this proposal, it’s only the curvature of the outer curve that determines the “overall” curvature.
To close the loop on this, the economics working group decided not to pursue this proposal, for the reasons I believe you are referring to. Ultimately, any Curator that had signaled immediately before the curve flattening would see an immediate unrealized loss. Also, even announcing the flattening of the bonding curve at the subgraph deployment level had the potential to trigger a “run on the bank” at the subgraph deployment level because the incentive would be to exit immediately to lock in the highest price.
The favored solution to avoid some of the harmful dynamics at the subgraph deployment level among the economics working group, at the moment is: GIP-0025: Principal-Protected Bonding Curves
