8 - Is It Possible To Create Routes Through The Admin Question: Is there a way for users to create routes in the admin? 

Issue: I have a bunch of nodes and tax terms that are being used in Views but no where else. They shouldn't be accessible to the public either. Changing their path to /admin didn't give me the result I wanted, where in D7, that would automatically set them to the admin theme and I could set the permissions that way. I haven't found a decent entity module to create them like I want either. 

Solution: Created a module that used a wildcard route. Then create a service that uses RouteSubscriberBase and alterRoutes to block any access to it without X permission. 

I think there is some potential for others to use this but cannot find a way to set the routes to be blocked through the admin.  x
You may want to check out the Rabbit Hole module. 


  Rabbit Hole is a module that adds the ability to control what should
  happen when an entity is being viewed at its own page.
  
  Perhaps you have a content type that never should be displayed on its
  own page, like an image content type that's displayed in a carousel.
  Rabbit Hole can prevent this node from being accessible on its own
  page, through node/xxx.
