It's not a fatal flaw. There are currently two or three proposals for solving this floating around the working group known as ATIS. There just hasn't been a consensus on it yet.
I believe the groups will get to a consensus, probably in the next six to eight months, but when the CRTC says it wants it done by September 30 of this year and the solutions to fundamental issues are still six to eight months away, those two conditions don't really line up together.
