Paths with excess routing data should not be permitted

[bparks]

For instance /home/ and /home/index should both be valid and should be equivalent, but /home/index/does/not/exist should not be a valid path

This requires tests to be written against more than just the routing code. The path should result in a 404 if and only if there is excess routing information after it has already been resolved to a Controller/Action and the action method is not a __call method and the action method does not take $opts.

In the case of a __call method, it is the responsibility of the ResourceController to determine if there is excess routing information based on the method that gets called. This almost calls for a refactoring of the routing logic to include some in individual controllers. (ugh!)

In the case of action methods that take $opts, it is their responsibility to validate the $opts.
