    being tired of finding '(Smalltalk at:someClass) notNil' all over the place,

    start to concentrate feature queries to this single class, which might get more

    feature methods via extensions.

    Thus, to correctly ask for a feature being present, use:

        ConfigurableFeature includesFeature:featureName

    or

        ConfigurableFeature knownFeatures

    to ask for a list of features.

    Caveat: just started; more will be moved to this place as time goes by
