Lower Back Assistance on Boring But Strong

Hey Jim,
on your BBB Beefcake Blogpost you said “NO lower back work is done (back raises, for example) due to the volume work of the lower back in deadlifting and squatting.” Is it the same on BBS, since it’s the same weights and the same amount of volume, only different rep scheme? Or is it okay to add some RDL/Goblet Squats as Single Leg/Ab Work on my BBS template, maybe even on Squat/Deadlift days?

Thanks!
