(Please forgive my potential ignorance.)

If I'm guessing right, the point of CONFIG_DEBUG_LIST being enabled
everywhere is probably more about hardening than debugging, and given
that since 6.6 we have a CONFIG_LIST_HARDENED[1], wouldn't it make more
sense to use that instead?

Or is the point here to exactly follow the typical distro config,
without regard to whether it's actually the optimal thing to do?
