Jeff:

Post 115 was from Popeye21 and his boat looks like it does have a "Brewster Bite" configuration which you refer to as 'standard practice' if I read you right. Our modification to Orion is less adventurous than either Popeye21 or Talisman -- we just added about 6" to the fore'n'aft dimension, i.e., chord, of the rudder. And filled in the prop aperture.

As to reasoning, I prefer the traditional configuration, rudder hung on the aft edge of the keel/fin/deadwater. The are pros and cons, of course. The separated foils in vogue now have a bit less wetted surface and produce more turning torque per unit of wetted surface. The configuration is more 'efficient' in at least the hydrodynamic sense. Probably.

On the down-side it is more prone to snagging and structural damage. And seems to require more attentive helm-keeping.
