Sounds like a GREAT idea!
It really does. But likely this will degenerate into finger-pointing between Google and the phone manufacturers. Google will be absolutely safe, no matter what, because the FTC will never do anything to harm them in any way.
If anyone thinks they will, see this article from El Reg last month. Google will just call a certain close friend in the White House, and the nasty FTC will go away and leave poor, abused Google alone.
Don't hold your breath waiting for any patches.
