You lose a lot of rigidity in the whole drive structure because that length of plate now has a nice spot to bend. Imagine taking a load straight through your direct driven axle and how that area will deflect with or without the flange.

The frame as a whole takes some steps to mitigate those potential issues. I didn't upload it today because the only shot I have of it available at work doesn't provide a lot of good information. The only drive components that'll pass through the outer plate are the two dead-axle bolts. There aren't any bearings or anything that requires very precise alignment.
The belly pan will connect to the outer face in a few places to counteract bending. It'll also pick up the inner flange and the gearbox flange. That should help to tie it all together.
If I can render a more useful view tonight, I'll put that up here. The model isn't anywhere near a finished state yet, but taken as a whole, I think it'll be pretty stiff.
