They must not have __init__.py files specifically to avoid *conflicting*
with this Twisted's twisted/plugins/__init__.py. Since the idea is
that, during installation, your foo_plugin.py will go into the site's
twisted/plugins directory, we forbid projects to make twisted/plugins a
package because otherwise one package would stomp over the other's
__init__.py and break things.
