I checked the timing again and it looks like the coming 7.3
(not 7.4) merge window is already for the LTS kernel, so it's
really only one cycle between them and I think it's worth
waiting for that so that any remaining users have something
they can run securely for a few more years.

Between your original patch (removing the Kconfig symbol)
or marking it as 'depends on BROKEN', I don't really think
it matters much because users will have to apply a trivial
revert anyway one way or another.
