Most consumers don't want to bother with oil analysis to determine proper drains - especially with bypass - manufacturers play it safe and recommend very short drains because most people don't even check their oil.
Well as the above posting said, manufacturers desgin the average vehicle to go about 250 -300k miles. Pre-Oiling will extend engine life beyond this - especially in colder climates, or when vehicles sit for extened periods of time (enough time for the oil to settle down into the pan).
PS: there was really cool show about oil last night "lube job" on the history channel, it was very interesting and they went over most of the same things that has been mentioned in this thread with scientists and chemical engineers from shell oil and some other companies. lube job
