How to guess when Chrome beta APIs will become stable

Question

I would like to know when Chrome's declarative web request API will be in the stable channel (https://developer.chrome.com/extensions/declarativeWebRequest). I realize that is asking a lot. I'd like to write an extension that depends on a beta API though and am just curious if there is a best approach for guessing when it might become stable.

Answer 1

declarativeWebRequest is not currently scheduled for promotion to stable. There were some issues with certain use cases that made the current design and implementation insufficient for the long-term support that stable would entail. We have not announced plans to proceed further with the API. You can star http://crbug.com/112155 for updates.

Answer 2

There is no way to guess when a Chrome API be become stable until it does. Priorities, features, bugs, etc make it impossible to predict.
