Description:

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
    ConfigurableFeatures knownFeatures
to ask for a list of features.

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