I'm really having trouble with this interest in "plugins" as opposed
to "rules for chains" and "handlers for pipelines".  To install a rule
or handler is a three-step process done by the site administrator:

1. Write or download a module containing some code using a simple
   plugin API; the code has access to all Mailman features.

2. Save/copy the module to .../rules or .../handlers.

3. Configure the global pipeline in mailman.cfg or individual
   pipelines in list configurations.

That looks rather "pluggable" to me.  What does a "plugin" give that
improves on this process?
