It doesn't really promote its use, but it's exceedingly easy to use cache headers with Next.js if you're using getInitialProps or getServerSideProps.

My issue with Next.js (alongside lack of nested routes) is that it has a handful of weird light abstractions which make things marginally easier for developers for the most common cases, but completely tie the hands of people who know what they're doing. To that end, Remix is a little more appealing.
