I've done this now, in a hardcoded way.  When you start with an empty
Data.fs, an Events service and an ObjectHub service are created and
activated in the root folder.  It feels like an improvement already.
And it should be easy to add other services as the need arises.

OK, will do.

Sure.  I also hear that the SiteDefinition should return a list of
directives instead of executing directives as it goes -- would that be
a good exercise?
