I also think an install script is a good way of facading the actual
process.  In fact for my pythonproducts product (allows one to use
python packages as zope2 products without the Products directory) I was
considering providing a py script to do this for zope2 products.  Zope 2
developers see zcml slugs and say, "what, things have gotten harder
going to zope3?".
