Exactly... and Remix is the old team from React Router, who break their API every version. I understand the author's arguments against Next.js, but having just set up a hello-world in Remix and being immediately confronted with a hydration error, I don't think Remix is the path forward either.
2 breaking changes from the 6 versions released. Also, releasing a "backwards compat layer" a year after releasing a version of a library doesn't mean the original release was not a breaking change.
