That doesn't sound like an issue with semver (or pragmatic). There is no versioning convention that will prevent people from being people. A rigid, automated (magical) versioning _system_ might do that, but not a convention/standard.

I find semver extremely helpful, both as an author and consumer. It may make me think a little for some packages about where I want to pin things, but at least it makes the mechanics of pinning them sensible.

Edit: packets -> packages
