AFAICT, the display of a 'note' is triggered by db_get in postinst.
Since postinst gets the previous version as arguments to an
upgrade/configure action, it's a simple case/if statement.
case "$1" in
configure)
case "$2" in
0.13*) db_get postgrey/subnet_upgrade_note;;

I say it would. But debconf doesn't hurt.
