> say LibA v3.0.1 vs LibB 1.0.0 – reveals something useful, such as, that LibA has undergone three major revisions, so perhaps it is much more mature than LibB. It can also mean that LibA messed up their API design twice and had to break BC twice while LibB worked diligently to provide a design that nailed it at first try or spent years in 0.XX territory and only called it stable when they were certain it's stable. I don't consider SemVer useful to compare the maturity of software components. It's not a statement about that. It's useful to get a grip on how hard it's likely to be to go from one version to the next one.
