There are actually some performance downsides to rotating, but you are trading for frugality and tire life
If your alignment is abnormaln rotating will just eat all your tires instead of only the one or pair of tires
The way to think about it is like grating carrots. If you rotate you are giving up tread contact and have worse performance every time you rotate. But in exchange you don't end up with a triangle carrot stub at the end and can get a few more grates in. but all your shavings will be shortened shavings rather than long shavings
Many would argue those last few grates are the worst part of the tire anyway.
Don't most BMW have larger tires/wheels in the back vs the front? So I can see why they wouldn't recommend it. Swapping side to side would be about pointless.
Most have the same tire front and back. Only the racecars really have staggered tires. remmeber how many x series bmws are out there too. not everything is a m4.
In Germany bmws are the domestic car they have cheap economy models too.
You can google the bmw recommendation.
I explained the technical reason already, and germans if anything, are technical. They will tradeoff ease of use, longevity, etc to be more technical correct, which is the best kind of correct

I dont think you can argue against the point that keeping the tire on the same corner gives it the best road contact after it beds in. The rotation is purely for lifespan and frugality.
If you choose to rotate for the extra lifespan that's fine because its your decision and a tradeoff, but just understand their point is also correct and what they say is technically true.
Pretty much all m3 and m5's have staggared tires.
