Laravel used to document nested routes, but although the functionality is apparently still there, it has been removed from the docs
The thing is, although its cool to have like /post/4/comment/56/rating/3. post 4 and comment 56 are actually redundant since all you need to service the request is rating 3.
If the ids were relative (ie the 56th comment of post 4) then the full url would be relevant.
As it is, its not worth worrying about as I can't see it adds any value
