What problem are you trying to solve?

I'm trying to write a plugin that accepts a function that receives the request as a param and it could be nice to have the generic from the route shared to plugins, something like the following:

// plugin.d.ts
interface PluginSpecificConfiguration<Refs extends ReqRef = ReqRefDefaults> {}

// routes.d.ts
interface CommonRouteProperties<Refs extends ReqRef = ReqRefDefaults> {
    plugins?: PluginSpecificConfiguration<Refs> | undefined;
}

With that, we could configure plugins like this

declare module '@hapi/hapi {
  interface PluginSpecificConfiguration<Refs extends ReqRef = ReqRefDefaults> {
    pluginName: PluginInterface<Refs>;
  }
}

I'm interested in writting a PR if y'all accept the idea :)

Do you have a new or modified API suggestion to solve the problem?
