I was looking to be able to go back more than one version and it seem like composes could allow doing that? Not all issues are discovered right away and may already exist in the previous version.
I did this just yesterday, going back to systemd-239-43. I noticed my problem on RHEL, which jumped from 41 to 45, but I am potentially able to write a better ticket by being able to reproduce it in Stream, if I can go back more than one version.
Could it make sense to base what versions are made available in Stream on what's between versions in RHEL? I have no concept of the limits on space though, particularly for mirrors.
