@rodfersou Because the community in general don't want yet another way to configure components (because of what happened with grok). This was discussed in plone-developers list when I was developing venusianconfiguration. Because of that, I released it only quite recently (because I needed it outside work repositories).
Also technically venusianconfiguration requires that
zcml-conf-additional = %import venusianconfiguration
in buildout, which would be different from "normal add-ons" just working.
