Yes. I endorse the above reasoning.

Maybe the glory of seeing "Linux 6.0" in the footer of the bpf-helpers
man page will inspire more kernel developers to follow that page's
example.

Looks reasonable to me, at a glace.

You've got a license named for you in SPDX now--you're stuck with it. ;)

I would add " (in preparation)" to the string, and have the script that
finalizes a release strip that out.
But even if you go with the garrulous output of "git describe", I have
good news. In groff 1.23, overlong header and footer material is
abbreviated with an ellipsis. (This was an educational experience in
string processing with groff.)
