I don't think changing this rule will improve the game in the slightest. To keep the game on the level that it has been, they should have just decided to start calling the rule as it was intended, not change the rule to fit their lack of accuracy. They haven't called travelling as it should have been called for a long time, but the solution should not have been changing the rule, but rather calling it as it should have been called.
How will we guage new records being set when present-day and future players will have an advantage that former players did not? Does anyone honestly think this won't change the game at all? Before this they weren't calling 2 steps, now they'll stop calling three. The whole thing is just an excuse to make up for their lack of bringing integrity to officiating. I, for one, wish they had left the whole thing alone, started calling travelling the way it should have been called, and given extra calls to anyone whining about it.
To think this will have no effect on the game, is very naive', to say the least.
