But that's been happening for ages, before the advent of T20. In the 2000s test pitches flattened out, which allowed Aus's new brand of attacking cricket to flourish, but also reduced batsmen's exposure to tricky pitches and the need for bedding in. I'm skeptical of the effect T20 has had on this aspect.
