We don't expose any endpoints that respond to these methods, do we? Why allow them by default?

[gertd]

I asked to expose ALL settings that are by default set by the service-host, as it is not clear what disappears when you set just one. Ideally service-host, would not set any defaults but only provide the means to set them, in which case the service needs to set/define what it needs based on its usage.
