I think they created another option by just lowering the holders - you can either shim the topdeck or add shims and screws to the layshaft as before. Plus now you can leave it without screws and shims, where it only touches the bearing which probably offers something in the middle in terms of flex.

The RSD layshaft bulkheads for the original T4 had the layshaft lowered .5mm with the stock bearing size and worked fine.
I'm not going to get in a passing contest, but having actually seen and handled the 17 at the world's.. I can categorically state that it is exactly as stated. The layshaft is not lower, just the bulkheads either side of the bearing have been lowered 1mm. If you don't believe that, then I guess just need to wait for the announcement.
I will conceded that the bearing does touch the top deck just on the current car.. although I had to check, as I normally have the top deck shimmed up!
