Looking at the code it appears steps (import and export) are not
registered for interfaces. Only profiles are. However, even that
registration by interface for profiles isn't considered in the ZMI in
the base profile or extension profile select lists that show up on the
Profiles and Import ZMI tabs.

I have now gotten things to work by going through all import handlers in
CMFCore and making sure they don't do anything if their handled content
does not exist. Some already failed gracefully, others didn't. Looks
like a simple oversight and lack of usage outside of the CMF.

Another item that does not work is the Snapshot tab and the export of
all steps when inside the PluggableAuthService instance. The failure
looks like this:

In the debugger I see that the object in question is a absolute_url
adapter residing in the base component registry in the site root. IMHO
the components exporter should not look at the base registry at all,
only a local registry if one exists in the folder the tool sits in. Correct?
