This is now ready to use from the Launchpad point of view. There's a
"proposed_not_automatic" flag on distro series exported over the API; if
this is set to True, Launchpad writes "NotAutomatic: yes" and
"ButAutomaticUpgrades: yes" to the Release file. We've also arranged
for *-proposed to be pinned to 500 in launchpad-buildd, so Launchpad
builds will ignore this; I can't speak for other build environments.
Thus, from the Launchpad point of view this is ready to use, although
somebody may want to check the behaviour of things like sbuild and
pbuilder first.
Somebody in ~techboard would need to make the actual change, if you
think it's appropriate. For example, the following in "lp-shell
production devel" would do it for all supported Ubuntu series:
for name in ("bionic", "focal", "hirsute", "impish", "jammy"):
series = lp.distributions["ubuntu"].getSeries(name_or_version=name)
series.proposed_not_automatic = True
series.lp_save()
