An accurate 8 3/4" rear axle width list

When I had my Dana cut down, I left the offset to factory. Didn’t see a reason to change it
The intent of having equal length axle shafts is to make having spares easier. The result of building a 9” to have equal length axle shafts is a pinion gear offset about 2.2”.

My question is…. Is having that much offset (about an inch more than a 8.75) a bad thing? If so, why?
