A very short sentence noting that navigation role/nav element might not always be required, with a link to the warning would be fine, I think.

Every group of links has navigation as its purpose, but not every group of links needs to be a <nav> or navigation landmark, no?

It’s going to depend on context, isn’t it?

I wish there were a document structure role like “region” that wasn’t also a landmark, wasn’t included in a page summary or ToC, but that took a nice aria-label. Is that role=“group”? What about <div role=“group” aria-label=“Breadcrumbs”>? (By the way, in your example, shouldn’t it be Breadcrumbs, plural? It’s a collection of crumbs, right? How far do you get on just one crumb? ;)

Otherwise, and I’m not suggesting this, but the web did at one point do DIVs with visually hidden headings…. 

Another pattern I’ve seen is to have the Breadcrumbs included in the <nav> element that also contains the main navigation menu, so you only have one navigation landmark with two sections in it, but now that’s getting more complicated on a few fronts.

Ultimately, my comment was largely spurred on by what I see as rampant overuse of landmarks, which defeats their usefulness in my opinion, and nothing personal against Breadcrumbs as navigation landmarks per se.
