These kinds of tricks are nice for progressive enhancement - you can have a navigation section in your server-side-rendered SPA that outputs a fully usable nav like this, and if a user has JS disabled, they'll still be able to navigate around your site, albeit with hard page reloads instead of more instant transitions. It's funny that people are using js frameworks to render js-free snippets that are then progressively enhanced with more js, but that's web development today.
