I think it wouldn't be a wise idea to tie initiative with your ability to win or lose a game.
You probably can build and fly a list that simply will deny all it's points for 75 minutes and then take the victory.

Seems super-unfun to me.
Also such kind of ruling would encourage slow play, which is something nobody should support.
Honestly I can't think of a simple way to fix this "we'll remove draws completely from the game" issue. Even though ID's may have been unpopular for some, they never had or would have had that much impact on the game as this new ruling will have.
I imagine a time victory will still be considered a modified win.
