What is the current behavior?

The experimental folder re-exports functionality and has done so for a long-time. Perhaps this has been long-enough and no longer needs to exist? I don't feel too strongly about removing this, but it does seem like noise that could easily be restored if necessary.

What is the new behavior?

Removes the //experimental folder because everything has graduated out of it.

Does this PR introduce a breaking change?

• Yes
• No
