I strongly disagree that it has no value.
If I interviewed a developer and they showed me an impressive website/application that was built without a framework, I would probably be more impressed than if they showed me one that was built with one. An understanding of the basic building blocks of the platform is always helpful, just like I would consider knowledge of lower-level programming and different programming paradigms a huge plus, compared to someone who's only ever done web.
I would, of course, also be sure to ask them about why starting from Adam & Eve is only rarely appropriate in a business context, how it's important to write code that others can pick up and understand. I expect anyone but the most junior candidate to understand that no tech stack is perfect, and that it's all about trade-offs, and that the tech is a means to an end. We don't hire people to love a tech stack (most of them are pretty unlovable, to be frank), we hire them to, as quickly as possible, get good software in front of paying users.
If you come in and demonstrate that you can take a thorough understanding of HTML, Javascript and CSS up to something resembling a dynamic, modern, responsive web application, and if we can have an intelligent discussion about what the frameworks and infrastructure bring to the table, you're obviously miles ahead of someone whose knowledge stops at copy-pasting React snippets and googling the WebPack error.
