speaking for Debian: Our release process is probably a bit too
unpredictable for a fixed date. We do, however, benefit from early
version bumps in the pre-release branch; the mtl/transformer transition
is still not finished in Debian (due to having to rebuild almost 200
packages and some architectures like sparc being a bit slow these days).
Knowing about the packages versions earlier means less work after the
official release of the platform.
