1) use `:update-paths` to handle data in certain (loose) paths differently
- accumulate schemas in all relevant routers into vector
- we do not know the coercion here (ring/http have special handling of data, e.g. http-methods)
2) run coercion compiler for the model to merge the effective model
- schema + malli = should work ok, spec = best effort
3) publish final schemas into compiled route data
