We added Prefs support back when it looked like it might become a
useful way to handle config in a JDK-standard way.  The idea of having
system- and user-specific config in a DIT makes a lot of sense and
similar mechanisms exist in Windows and Linux.  To answer your
question, it would be useful if Prefs ever became widely used.

At the same time that Prefs hit the JDK, there was a push to add Prefs
as a standard service to the OSGi Service Platform.  So, we add Prefs
to the core of ApacheDS and there is a Prefs OSGi service in my
sandbox, which pretty much just wraps the ApacheDS core prefs with the
OSGi Prefs API.

I don't think it should be part of the core.  If possible it could be
its own module or even rolled into the OSGi Prefs with ApacheDS as a
pluggable back-end.  But, going back to the fact that Prefs hasn't
taken off, I also wouldn't be opposed to just removing it.
