March Fast Track and Restictors

Did anyone get a chance to digest the posting about restrictors in the March Fastrack. It looks like it has not been approved but if so will go into effect in March? Am I reading that right? I did not get a chance to read it closely but I think it was 37.5mm for most engines. Thanks.
