Are breadcrumbs still relevant with interlinking?

Are keyword rich breadcrumbs still a beast practice when setting up navigation and internal links within the website?

Breadcrumbs are clearly useful but I would make a distintion between two perspectives:

1. Google: breadcrumbs are strongly recommended as part of a structured data implementation in order to get a clearer picture of our site's structure.
2. User: breadcrumbs can a be lifesaver when site structure is so deep that main navigation is not enough.

I usually skip the use of breadcrumbs for very simple structures and make it a must for complex and deep structures like ecommerce sites. For those cases in between I go for the better ux.
