Google: Too Many Heading Sections Is A Waste Of SEO Time

Google's John Mueller responded to a thread on Reddit saying that having too many heading sections, like as deep as H6, can be a waste of time for SEO. He said "Having this many sections is almost never going to make sense, and changing anything in the last level is never going to change anything with regards to SEO. This is a waste of time when it comes to SEO."
