Exactly! IMHO it comes down to the very basic saying--I think we do tend to overthink it. Most of us could buy a new bike, change the oil as specified using any brand of oil that meets the specs, and the bikes would serve us fine as long as we own them. For instance, I used plain old Pennzoil for decades before going to Amsoil and never had any problems that I'd consider to be oil related.
We come to these forums and argue oil nonstop, and how often will anyone tell you they had ever been wrong? Virtually everyone says they've used what they used on the interval they chose, and it works well for them -- everything works.
Clean oil good, dirty oil bad.
Whatever oil (and filter) someone chooses to use, when replaced regularly, will do the job just fine.
