I would love to read it. I noted and am worried about the dependency thing, though I think that would still happen anytime they were all in the app/bundler regardless of engine use or not. For "knowing what's enabled" we use the BootInquirer I mention, though we've never had to to know at runtime. The interesting stuff comes up when we have to sync the routing to our load balancer, which we haven't fully automated, though it seems possible.
