Add experimental `concurrentFeatures` option #24612

devknoll · 2021-04-29T18:46:55Z

WARNING: DO NOT USE THIS

I'm kicking off development on concurrent features. This is highly experimental and unstable. It will change. Please do NOT use it in your apps.

To begin with, this PR adds a highly experimental concurrentFeatures: boolean configuration to gate API changes. Additionally, it adds the start of one such API change: errors + tests to ensure pages/_document is a functional component, rather than a class. That's because it's eventually going to become a React Server Component.

More coming.
