I would like to highlight Lennart's point. We need to be very careful
here. We would only have an illusion of improvement if we'd end up with
less directives but more long dotted names into Python packages. I'd
argue that this might make ZCML *harder* to understand, not easier.
In fact, I wonder what a ZCML would look like that focused on reducing
the amount of dotted names in use...
