The settings are a bit buried indeed and I was hit by that myself at one point when upgrading the kernel using old .config, but honestly I think we want to let people strip the kernel from options they don't want or need, so I think it will best be sorted by presetting the useful options in the respective defconfigs and then maybe guard the more critical ones with `if EXPERT'.
