You don't have many options.

You can check the status of the nsd3 package when you install/upgrade nsd
and emit a warning pointing to some README.Debian that explains how to
clean up the situation (or you can do it automatically, it's not very
clean but should be rather straightforward).

Or you can add a dependency on nsd3 (>= 4) to nsd for the time of a
release cycle, thus forcing the user to keep a dummy package around.

In any case, I would still fix the nsd package to not remove the user on
