`/lib/modules/.installed` should include kernel version - right?

[consideRatio]

I think I've run into an issue where headers are installed, but the kernel version has changed over time. Could this make sense? If so, I think there is a bug related to this here, where the .installed file is created in a way that ignores what kernel version is installed, even though it may have changed over time.
