Upstream can change the ABI as much as they want without bumping the SONAME providing that the old interfaces are also present. It's entirely possible to end up with a situation where external binaries built against 1.0.1 won't run on 1.0.0 - the problem isn't limited to subpackages.
Sure. But in this case, upstream isn't changing the public ABI.
It's a different level of mistake that's being practiced here.
What difference does it make? Even if you stick to the public ABI you can't guarantee that a matching SONAME is sufficient. You need to depend on the package version you build against.
