Are there solutions in the space of having glib2.0-0 continue to exist as a package depended on by glib2.0-0t64 or depending on the new library allowing you to replace the postrm? That might create a space in time where glib2.0-0.so does not exist, but we probably have more flexibility there than we do with essential packages.
