How so? Semantic versioning shows no indication of project status. It's just a set of numbers that defines the impact of changes since the last set of numbers.
I'm pretty sure SemVer allows for alpha and beta releases. Why not extend that versioning convention to include an omega release as well? (Is "omega release" even a thing? I'm imagining it as the last stable release - it will be maintained but no new features will be added. Which I think I would consider different from EOL.)
But even a release titled “Final-1.2.8” releases a year ago doesn’t tell you if the last release was because it was abandoned and shouldn’t be used anymore because it’s out of date or if it still works and just hasn’t been updated because there was nothing else to fix right now.
