How do other languages do it? Python has the PEP process for discussing design on paper, but I don’t know how they handle experimental implementations.

Standard library packages can be declared "provisional": https://www.python.org/dev/peps/pep-0411/

The PEP says "A provisional package is one which has been deliberately excluded from the standard library's backwards compatibility guarantees."

But there's no equivalent for language features, AFAIR.
