Type RA, S209, and different oil compared to the standard STi

This is old information, but I've only stumbled upon it now... How is it that STI (and not Subaru) recommends 5W-40 oil in the Type RA and S209, whereas the standard STi models are still 5W-30? Shouldn't this change the entire scope of the lineup and apply this to the standard STi as well? Especially since the 2019 and 2020 standard STi models have the 2018 Type RA engine and transmission? Does SOA (or any manufacturer for that matter) have a contract agreement to sell specific oil viscosity and weight for their vehicles?

We are pleased to announce that Subaru Tecnica International Inc. has approved Motul 300V Power 5W-40 for WRX STI - S209. After having carried out extensive tests with the engine oil on our test rigs, on testing grounds and on the road, we approved Motul 300V Power for the vehicle.

Only semi-related....my M5 originally came with an oil "recommendation" (it's German, they're not recommendations, they're RULES) for a 10w60 in the manual. Later years were changed to 5W30 in the instruction manual. So 5W30 vs 5W40...meh? Rumor was the original mfg (Castrol) stopped making the 10W60 so they switched to a new OEM with a different weight.
