### Features

### Avoiding permanent beta

From Kubernetes 1.20 onwards, SIG Architecture will implement a new policy to transition all REST APIs out of beta within nine months. The idea behind the new policy is to avoid features staying in beta for a long time. Once a new API enters beta, it will have nine months to either:

 - reach GA, and deprecate the beta, or

the // runtime. The indicator starts at indicatorUnset after a reset. Invoking an // approved service transitions to indicatorTrue. Invoking a non-approved // service transitions to indicatorFalse, and it can't leave that state until a // reset. The idea is that functions can "delegate" checks to inner functions, // and if there's anything non-approved in the stack, the final result is // negative. Finally, we expose indicatorUnset as negative to the user, so that // we don't need to explicitly annotate...
