Not quite. Zope only calls the registration ("initialize()") function in
your main __init__.py module, so if you want sub-packages to have
registration occur, you must have the main registration function call the
registration functions from your sub-packages. See ZPatterns' main
__init__.py for an example of this. I personally dislike having a
monolithic initialize() function, so I always have the __init__.py
initialize() call an initialize function in the individual modules or
subpackages.

No reason at all. However, technically you'd be using PlugInContainers,
since only PlugInContainers can contain PlugIns. ZPatterns does this all
the time - note that a Specialist is a PlugInContainer, which can contain
Racks as PlugIns. Racks are also PlugInContainers, and support Data
PlugIns being plugged into them. LoginManager does the same thing, with
data PlugIns inside of UserSources inside of LoginManagers.
