You will have to test with both sarge and etch dpkg (until after etch
releases).  Colin Watson recently wrote [0] about one of the ssh bugs
and how this was complicated for him.

package, since the postinst happens after the conffile prompts, and since the
postrm happens post rm...

For sarge dpkg, your logic is correct.  AFAIU in Colin's case (perhaps only
because of the Replaces) the logic causes at least as many problems as it
solves, since etch dpkg specifically and deliberately prompts the user about
