This is my manual. The two sides to it:
1) The manual says so, BMW knows best, it helps with seals and setting mechanical parts.
2) The concept is outdated and precautionary (and maybe even CYA)...and you especially shouldn't sit at one extreme and baby it for 2000 miles and then run it hard.
And of course there's nothing really proving one or the other, just individual experience.... I'm not going beat it like a rental, but not going to really worry about it, either. Going from a 3 speed to 8 speed, 4500rpm seems like it would be hard to do for normal driving outside of maybe eco mode.

Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:
▷ For gasoline engine 4,500 rpm and
100 mph/160 km/h.
Avoid full load or kickdown under all circum‐
stances.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Due to technical factors associated with their
manufacture, tires do not achieve their full
traction potential until after an initial breakingin
period.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimized
contact and wear patterns between brake
discs and brake pads. Drive moderately during
this break-in period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
