• The FixedByPackageRelation and the sorting may be two different things, are they?
• call that may be "version_rank" and I would make it a float so that you can always insert a version between tow existing versions without having to change anything else
• Why not put that on the Package? this is package-level IMHO
• We need to have a default value of something like 0? and then only look at packages that need to be updated

We will be storing all packages sorted as per this meta

ordering = ["type", "namespace", "name", "version_rank", "qualifiers", "subpath"]
