Vercel has slowly taken over Facebook's position as being the employer of the main developers of React. There's a debate to be had over how much they 'control' it or not, but the fact create-next-app is the first recommended option on the official installation page now does show it's had an impact.

5 or so years ago, Next was a pretty solid option to quickly build up a non SPA, when combined with the static export function. It wasn't ideal, but it worked and came batteries included. Over time it's become more bloated, more complicated, and focused on features that benefit from Vercel's hosting – and static builds can't take advantage of them.

These newer features seem of limited benefit, to me, for even SPAs. Why is there still not a first class way of referencing API routes in the client code that provides typing? Once you reach even medium scale, it becomes a mess of inteprolated string paths and manually added shared response types.
