Google is not a lawmaker, and if they continue to release 0-day exploits in this manner, even after being instructed otherwise by the vendors, at some point they will be made to shoulder some of the burdens of their having done so.

Your speculation about the reasoning for the extension could not be more off. All you have to do is read their blog discussing their disclosure policy to understand why those exist.
