Topic Clusters: Recommended/Related Articles at Bottom

At the bottom of cluster pages, do you have the Recommended/Related Articles showing there?

I noticed Backlinko doesn't at all.

Diggity Marketing doesn't either, only has categories listed on the side bar.

Neil Patel doesn't either, but it looks like he has the pillar pages listed on the side bar.

What are your thoughts on this?

as long as their internal linking, bounce rates and TOS are fine they don't need "recommended articles". That's why these things are for (to keep people on the site)
