I take it then you are volunteering to test with and without the config

Even if the config option is kept I intend to rip it out every time I
wind up touching code with it in. Config options have a real cost in
testing and development.

For a config option that no one has come forward with an actual real
world use case for disabling, that cost seems much too high.
