But *some* user service needs to be available.  This is to my mind a
core component of Mailman in any case.  I don't see why having a
single interface (with perhaps a REST "binding" for IPC and a direct
zope.interfaces binding for within-process use) and a default
implementation of that service as a core component (but separate from
the post routing and delivery and admin routing and handling services)
would be very costly in implementation and maintenance, but it ensures
the flexibility to deal with unknown future requirements everybody
says is important.
