When relying on a third-party package with ZCML configuration, it is
sometimes desirable to disable certain directives, for instance when the
third-party package defines an event subscriber that you'd like to
disable. This is now possible with z3c.unconfigure.
While zope.configuration (the package that implements ZCML) itself
supports overriding existing configuration and the zc.configuration
package supports excluding whole ZCML files from being loaded,
z3c.unconfigure allows you to disable specific directives.
