It is not possible so it should not be in the API let alone in the example section of the docstring (I removed it).

Alternative is to re-enable the default values that were possible in from_values(). When we still had them, this was valid.

Problem is that from_values() is part of CanCurate which dictates most of the Feature API; so, it's not 100% straightforward to remove it.

Maybe we should re-enable the defaults so that this becomes meaningful again.
