It would probably be much simpler and safer to modify traversal instead
of replace the ZODB root object. Grok users should create application
instances, then select one of those instances as the application to make
visible at the root. The traversal process for the root folder should
automatically traverse to the previously selected application even
though its name is not mentioned in the URL.
In fact, I half expected to find a button to select the root application
when I first saw the admin UI. Moreover, the Grok admin UI should be
one of the applications that users can select from. Finally, there must
be some alternate entry method (a different port?) that lets users visit
other application instances even after one has been selected for the root.

The Zope world is full of misnomers, but we've succeeded at fixing them
in the past. Keep at it.
I might replace site with "configurable location", because most (all?)
containers are also locations and the only thing that distinguishes a
site from a container is that a site is able to modify configuration
