I still think it would help if you would work more on articulating what
problem you are trying to solve with the linux-headers versioning
change. I have read multiple versions of this proposal, and your
follow-ups, and I still do not understand what is prompting the
linux-headers change.
My intuition mirrors others in the conversation that it is problematic
to support multiple kernel versions without also supporting multiple
header versions.
