My 2 cents.
The 77/78 CB750F bikes included some changes to shed heat from the oil system. The sump has larger fins. An additional spacer was added under the oil filter housing - an oil cooler. My point is that mother Honda made some changes to help cool the oil for that particular bike/engine.
I doubt that anybody would argue that there must have been some need in order for Honda to make these changes to the 77/78 CB750F bikes. Therefore, I believe it safe to conclude that the changes were made in response to the output of that engine. An input could have been a desire to keep oil change intervals at 1,800 miles - meaning that it was possible to exclude these changes to shed heat, but a decrease the oil change interval to 1,500 miles similar to the K0 bikes would have been required. Another input may have been the comparable lesser maintenance requirements of the other competing motorcycle brands.
Regardless, I also believe it safe to conclude that if the output of our engines is increased beyond the 77/78 CB750F engines, either a supplemental means to shed some heat is needed - or the oil should be changed more frequently. I think we would all agree that oil change intervals should decrease as operating conditions get worse. To upgrade your engine and not alter something to account for the extra heat just isn't wise. You'll need to either get rid of that heat, replace the oil more often, or possibly use a higher quality of oil (that can cope with greater temperatures).
The benefit of properly sized and thermostatically controlled oil cooler to a stock (or nearly stock) bike is that you could extend the oil change interval somewhat or preclude the necessity of going to better oils. Certainly no harm would occur.
