To break-in or to not break-in?

Hey guys, I'm picking up a Golf R soon and I've been reading very conflicting opinions on a car's "break-in period".

Some folk are saying that they are broken in from the factory, and that we can drive them as hard as we want from day one. Some also say that the "break-in" period in its entirety is a myth.

On the other hand, there are people who swear by the break-in period and say that it'll do wonders for how long your vehicle lasts.

I know there are many opinions out there, but what is factual for a Golf R MK8.5? Does VW break them in during the building process, or is that something that the car owner is responsible for?

The manual does mention a break-in period, but I’m curious how much of that is mechanically necessary versus VW being cautious. For the MK8.5 Golf R specifically, does VW do any meaningful engine break-in at the factory, or is the owner still expected to follow the manual’s first 1,600 km guidance?

It's hard to find the “correct” answer to this question, and I'm hoping some of you guys can point me to the right answer, either via documentation, engineering explanations, or other official means besides “me thinks this.”

Edit: looks like i got my answer lol, i guess i was being impatient. Maybe i'll commit to a long drive to break the car in over the weekend. I will respect the break in period and the manual.
