[Debconf-devel] Bug#989567: debconf.postinst is completely unnecessary unless upgrading from pre-etch

Package: debconf
Version: 1.5.76
Severity: minor
Tags: patch
$reasons got me looking into debconf.postinst. I read it and figured
that it would only do non-trivial things when upgrading from a release
that predates etch (i.e. old-old-old-old-old-old-stable). Nothing in
there is useful for current upgrades. Can we drop it entirely?
