Document supported feature flags for experimental behavior

[brettimus]

Do you want to request a feature or report a bug?
Feature (documentation)

What is the current behavior?
There's no place to check how to opt into experimental features, or which experimental features exist. I stumbled upon draft's internal feature flag, as well as the gkx helper that's used to check for feature flags while trying to solve on a project #1063.

What is the expected behavior?
There could be a small document exposed to developers that tracks experimental features (that they could opt-in to).

I'm aware that this adds documentation overhead, but on the plus side it gives added visibility to what users can maybe expect in the future from draft.

Thanks for reading, and I appreciate your work! The draft learning curve has been steep but enlightening in many ways. It's really cool what you can do with this lil library.

Thanks for suggesting this enhancement @brettimus, and strongly agree with the steep learning curve. I'm still familiarizing with the project myself, as I'm not working on projects that use rich text editing surfaces.

Please let us know what would've made your learning experience smoother if you like! 🙏
