This is what I tried to make clear up thread at the time: there is no need
for a unanimous decision among flavors about whether to drop i386 images,
/so long as/ i386 is a supported architecture in the archive for the devel
release. The real question is whether i386 is still supportable (and
justifiable) as a release architecture at all in the 20.04 timeframe.
There are significant technical concerns raised about whether we can
continue to provide the expected security support for i386 over the lifetime
of Ubuntu 20.04. Certainly, we know that running a 32-bit i386 kernel on
recent 64-bit Intel chips makes for a weaker security story today than using
a 64-bit kernel; and as usage of i386 continues to decrease more broadly in
the ecosystem, we can expect it to increasingly be a challenge to keep
software in the Ubuntu archive buildable for this target.
In preparation for the possibility that we will not want to ship i386 in
20.04 LTS, automated upgrades to 18.10 were disabled on i386, enabling users
of i386 to stay on the LTS which will be supported until 2023 instead of
being islanded on a non-LTS release supported only until early 2021.
A final decision about whether to discontinue the i386 port of Ubuntu for
20.04 LTS will be made around the middle of 2019.
