So, you agree that the number of ZCML directives should not grow too
much, yet you say that you want to keep people adding new directives.
That doesn't add up for me.

Per se, they aren't dead chicken for me either.

That's not quite what it is for me. Rather than a package-afiliation,
namespaces currently seem to indicate usage (browser:view vs.
xmlrpc:view). To use namespaces for this seems arbitrary. This is also
along similar lines of the "The distinction which goes into what
namespace is highly inconsistent" problem. Why would security-related
stuff not have a 'security' namespace, but 'browser' stuff does?
