maybe we should have the tooling support that? Elm does try to enforce correct semantic versioning. Maybe swift-pm should do that too?

See http://elm-lang.org :
Enforced Semantic Versioning

Elm can detect all API changes automatically thanks to its type system. We use that information to force everything in our package catalog to follow semantic versioning precisely. No more surprises in PATCH releases!

I have no idea how well it works but if we'll end up relying on proper semantic versioning, tool support sounds like a good idea to me.
