I don't think we (as OE) should help people to do bad things; people
are good in inventing ways of doing bad things and we should try to
provide them guidance to avoid those, not promote tools to help them
in doing bad development practices.

OE-Core shouldn't handle and maintain this infrastructure, in my view.
