Full semver is an illusion. It's often debatable what is a new feature (we support a previously unsupported functionality) vs. what is a bug fix (it did not work correctly before). Also what is a non-compatible change is not always clear. Did the user do it wrong in their existing code or did the project make an incompatible change? The kernel has said for long times that they don't make incompatible changes. We don't break user space as they say. So you could prefix their numbers with an imaginary "1.". Of course sometimes opinions vary, whether a change breaks userspace or breaks wrong code. That said the kernel numbering scheme is weird. Increasing the first digit after 19 *or* 20 is less logical than imperial units.
