Why is there a need to do this rn? it's possible this logic won't even lie within our codebase until we reimplement markets in rust

[dutterbutter]

I don't think there is a need to do this right now hence the low priority but wouldn't we need to implement this when we integrate with markets?

[austinabell]

Depends on how the markets are integrated, it's possible this lives outside of our node
