I think we should remove the Recommends, actually looks like we already
had a delta removing it:
popularity-contest (1.70ubuntu1) groovy; urgency=low
* Merge from Debian unstable. Remaining changes:
- Set debconf question priority from "high" to "medium".
- Remove mail-transport-agent recommends.
but it got lost in the 1.71ubuntu1 upload to Impish.

Title:
Upgrades from Focal to Jammy pull in Postfix
Status in popularity-contest package in Ubuntu:
New
Bug description:
Steps to reproduce:
lxc launch ubuntu:focal reproducer
lxc exec reproducer bash
do-release-upgrade -d
Expected: no Postfix debconf prompt
Actual: Postfix debconf prompt
This is bad because there's a debconf prompt at all, but also that
users don't really know how to respond to this one because they're not
the ones demanding an MTA.
Why is Postfix being pulled in on this upgrade? After the upgrade, I
see that the only thing that Recommends default-mta | mail-transport-
agent is popularity-contest, so I think this package is the culprit.
In Focal, was seeded in the standard seed which is why it was
installed. However, the version in Focal does not have this
Recommends.
In Jammy, it is no longer seeded (https://git.launchpad.net/~ubuntu-
core-dev/ubuntu-
seeds/+git/platform/commit/standard?id=82c97be2eee777cb2f579474259cf86e51fe3a8f)
but since it was installed previously, the upgrade causes Postfix to
get installed during the upgrade process.
A possible solution is to remove the Recommends in an Ubuntu delta.
