I assume this idea is derived from the structure proposed by eigenlayer. Some shared security marketplace to match supply and demand between providers and consumers.
Even though we think the idea seems appealing on paper our long-term vision lies on a different forecast. We think the Cosmos market for security should be multi-layered between full set ICSv1, partial set opt-in V2 and eventually imagine subset security V3 with less validators involved to match lower costs execution demands. The hub’s position in this world is heavily reliant in validators to be proactive instead of passive. This is something we have described in greater extent here: Cosmos Ecosystem : A permissionless B2B2C network - #8 by Govmos.
In conclusion, we tend to support the thesis for governance approved onboarding for V1 and V2 requests. Where V3 type requests are expected to be more discretionary business served by validator subsets. This is where we would imagine a market fit for permissionless deployment.
