You are missing the point entirely. All of those examples you've listed are clearly marked in some notion of "prerelease". Even in the FreeBSD example, you're going to see that one version is labeled in such a way to make it sound safer. "Long-Term Support" labelling of one version says nothing openly about the unlabeled version.

It's exactly the lack of label on non-LTS versions I'm talking about. It has a real impact on people, looking at which version to install, and having no guidance that "this version not labeled in any special way, yeah, probably don't use that". And no, digging into the developer mailing list to figure out what the versioning malarkey a particular project is using is not a documentation of it.
