Don't you find it problematic, as a framework that's 8 years old to already have reached version 15.x? Assuming they follow semantic versioning and those are 15 different backwards incompatible upgrades?

Most of our upgrades have been fairly painless. Yes, they're not CI-succeeds Dependabot merges, but usually it's basically running the auto codemod and you're done, though I do always scan through the release notes and migration guide. That seems justified for the backbone of our application.

I haven't used next.js but it looks like they have mostly automatic/codemod migrations

`npx @next/codemod@canary upgrade latest`

Don’t think it’s semver.
