Actually I don't think that's what we are saying at all. Simply that coolers may be specified for a particular transmission (and in my case also a V-drive) but when using that transmission in a boat that that has a much smaller engine
and load than the maximum rating of the transmission, then that transmission will of course run much cooler and an external cooler may not be necessary.
Boat builders will generally go with the more conservative approach and install the cooler if specified by the manufacturer to avoid claims and concerns from the customers. If you want to assign more nefarious motives to the practice I can't deny it could be possible.
