Registering a tool isn't a dead chicken:  it is the mechanism which
allows software developers to offer "candidate local utilities", which
can then be added / configured by the site admin into a local site
manager later (one is mechanism, the other is policy).  In the global
site manager, there is no need for the equivalent registration because
the policy is in the same place (the site's ZCML).

Most tools will *not* be in persistent modules;  they will be persistent
instances created from filesystem software.  I do not expect to depend
on persistent modules for CMF 2.0, for instance, for at least a year.

The particular dead chickens I complained of (in the attachment to my
original message) were the need to register factories / menus / menu
items in order to test the site manager view.  Those sacrifices were due
to an (expedient, I think) choice to reuse the "content add menu"
machinery inside the site manager.  None of that is needful or
interesting, given that there is *zero* overlap between the kinds of
things which one might add in content space versus site management space.
