What I would say is that when you actually come to be lying under the car performing the surgery & having to use a hex wrench through the hole, you will probably welcome as big a hole as you can get! Although, width is probably more important than length if you see what I mean.
Your photo also nicely shows how MMC use a star washer on top of a plain washer to attach the outer Centa housing to the crank. doh
