+1 for dropping images at the beginning of the LTS meta-cycle, instead of at
the end. It avoids setting wrong expectations that i386 will continue to be
supported, it saves us effort carrying it forward, and it also gives us
more room to reverse course if it turns out we were mistaken about the need
to continue carrying those images.

As a practical matter, as long as we are carrying the architecture in the
archive for a release, we have a requirement internally for some sort of
cloud image for that release (whether or not this is supported publically)
and a kernel to boot it with. And this base image would need to be de facto
security supported, even if there is no official security support for the
packages in main.

We have the capability to mark different support periods in the archive by
package×architecture, and should certainly do this. Most people don't look
at this information, however; I think that for packages that we know won't
be LTS security-supportable on a particular architecture, we should consider
dropping those binaries from the archive as well.
