In all seriousness, these changes have been made to further T20fy the format. Now the batters have less time to "settle-in" during the PPs and will be expected to take more chances sooner. They're expected to be aggressive from the 45th over anyway, therefore the requirement to take the last PP before the 40th makes sense. The two bouncers per over rule will make things more interesting for the fielding side, provided it has guys who can bowl those on a variety of pitches without being hooked or pulled out of the park.
That being said, fielding restrictions favor the batting side BY DEFINITION and future HOFs and worldclassy total batsmen like Nazza!, Rocky and Imzie will excel under these rules. I'll be sure to bring my um-be-rella because it'll rain sixes when these guys don the green and red. Nazza!'s wicked bouncers will add yet another dimension to our world beaters with the incomparable trio in it.
"And do not curse those who call on other than GOD, lest they blaspheme and curse GOD, out of ignorance. We have adorned the works of every group in their eyes. Ultimately, they return to their Lord, then He informs them of everything they had done." (Qur'an 6:108)
