I believe the entire use case you present was already acknowledged in the comment you are replying to, I. e. the “easy interface” to “exclude certain routes”.
The comment I was replying said that the functionality might be useful. This does not acknowledge any particular use case for the functionality, and leaves open the possibility that it might not be useful. Someone who isn't sure whether this functionality has legitimate uses or not probably isn't aware of what the legitimate uses are.
