Risks

Interoperability and Compatibility

The API add a new method to pre-exist Intl method to expose available values for some of the option and should improve interoperability between Intl object and help web developer to figure out compatability issues between browers.

Web developers: No signals (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/supportedValuesOf) MDN link

Other signals:

Ergonomics

The return result of the newly added API could be used to call pre-existing ECMA402 API.

Activation

Should be straightforward since it is adding a new method to pre-exist Intl object and leverage pre-existing concept and property key and values.

Goals for experimentation

Reason this experiment is being extended
