This is more true for some products than others. I worked on one product which involved a massive store of XML documents and a suite of somewhat complicated serializations and transformations. It was the right architecture for the project, for sure. And it was definitely the fundamental gene of the product; all of the product's design had to flow from this XML-heavy information architecture and backend. But most of the products I've seen are not so unique. For the vast majority of web products out there, simple CRUD apps backed by a relational database, I don't think the information architecture needs to be front and center in product design conversations. People can make assumptions about this kind of app and they usually won't be too far off the mark.
