How to get the routes available for the authenticated user

Question

I'm setting up FOSJsRoutingBundle on my app. When doing this I realized that the endpoint that returns all routes for the app, there was returning all routes for my internal app. I was digging in the source code, and they didn't apply any filters to the routes returned based on user roles. This is very insecure way of doing things, because for me I can't reveal all the internal routing configuration for my app, because it will lead a security breach, if someone used for example DevTools from chrome check for access to every route in my internal app. The question is, there is a way of accomplishing that, return only the routes accessible for the current user?
