I disagree. Just because it is simple to create new ZCML directives
doesn't mean we don't have to. The less special ZCML directives there
are, the less people need to learn and the more people can reuse
reoccurring idioms. That's a good thing. If we can pass on architectural
simplifications to the developer who's writing Python and ZCML, we
should do that.
