I've been turning wrenches professionally for forty years, you do it your way, I'll do it mine... Most inner seals leak due to damage or a plugged housing vent..
Recently installed seal often fail because the garter spring popped off when installing the new seal, or the seal housing got distorted... Or the seal wasn't driven in fully and the bearing retainer ring rubbed on the seal...
Grease is heavy and generally isn't difficult to keep inside the bearing, especially considering it is being thrown outward by centrifugal force and the area where the seal lip rides is the inner most point of the axle shaft....
