I think folks are just going by what's in the owner's manual to avoid any potential repercussions... that's all. I'm sure the MS-12991 spec is fairly new, hence why not a lot of manufacturers have it, and it probably cost $$$ to get an oil certified.
You do what you want to do... but I took my '21 Gladiator EcoDiesel in for an oil change, noticed they put in T6 (after they told me that would put in MaxPro), and had them drain it. Again, it's a new engine--I'm not going to deviate from what is recommended. It's got to be there for a reason, right?
