Imagine package foo-player with two debconf questions, gtk-theme and 

 1) install foo-player, and select "green" and "JackD"
 2) edit /etc/foo-player.cfg to "theme = blue"
 3) preseed new value for audio-bus "Pulseaudio"
 4) run "dpkg-reconfigure --favor-answers-over-pkgstate"

Result would be that *both* theme and bus would be changed.

I have now raised the question at debian-devel at l.d.o - let's
discuss technical details there instead:
