I think that it depends a lot on how much customisation you have to do on top of NextJS to make it work for your personal use case.

For example if you stay as close as possible to the framework defaults, everything is golden. But as soon you start pushing it to the limits the cracks start to appear.

Last year I was working on a NextJS app with 15k files, 18k unit tests, 100+ developers in the same repository and a page with hundred of millions of page views daily. Under that conditions NextJS doesn't scale, but again, those conditions are not the majority of the NextJS cases.

In that project, we have been using NextJS as a standalone for around 5 years and each time NextJS rollout a major version it take us at least 2 months to be able to upgrade and keep it working.
