Hi Mason, Thanks for starting this discussion! The proposed Source sounds awesome and we would be interested in taking a look at the source code and evaluating our use cases. We can provide information and review on a potential FLIP based on other use cases.
Do you have a fork/branch that you are working with that is public? Could you attach that so we can start looking at it? Let us know if you need anything from us to help move this forward. Thanks!
