RFC: Clean-up of old kernel ABIs at point releases

many people with the discussion]

Hi,

When the kernel ABI version has been increased between two point
releases, we currently remove the old versions as part of the point
release, to avoid carrying cruft.

This has unfortunate side-effects for a number of use cases, including
CI setups which immediately stop working as the packages they attempt
to install no longer exist in the archive.

If we were instead to change this policy to, for example, remove the
packages after the subsequent point release instead, can anyone see any
problems that this might cause, whether for tooling, tools or anything
else?

Regards,

Adam
