I'm probably at least as opinionated as anyone in the forums, and have been wondering about that lately. Not offending people is probably going to be job #1 in the future.
My new M1A came with explicit instructions to grease sparingly but with deliberation in several areas. Why would that be important for only one type of firearm? I think what is important is the area of load, the pressure and speed of the friction, and time between applications/cleanings. Ideally keeping parts separated during action would be best.
If we see bluing or parkerizing being worn away we know the pressure is too high to keep parts separated, they are making contact through the lubrication. Lightly loaded large area sliding surfaces could probably work best with oils, and such surfaces will be slowed down by grease. Small pins in holes are "captivating" for oils, the oils are more likely to stay put. A gunsmith with many years of experience could probably point to places in most common guns that seem to wear out too fast, such places might need grease even if they are pins in holes.
Greases tend to keep surfaces separated better than oils, all else being equal, oils work perfectly in enclosed pressure lubricated places, even aluminum will wear well with pressure lube and correctly toleranced journals.
Highly loaded areas always get grease in my guns, areas that show inclination to wear get grease. Wilson's Ultima.
