> is that actually a category page?

What the parent commenter is referring to is actually called a Navbox (https://en.wikipedia.org/wiki/Wikipedia:Navigation_template). Like @chatmasta, I think it would be interesting to label those types of links distinctly and allow excluding them.

Or perhaps alternatively, exclude the contents of those navigation templates, but allow using them as an additional node: David_Bowie -> Template:Grammy_Lifetime_Achievement_Award -> Enrico_Caruso. (In this case, that is redundant with the main non-template Grammy_Lifetime_Achievement_Award page.)
