Listen to yourself , your unimog had plain steel lines and they lasted almost half a century... and unimogs are filth encrusted off-road beasts and that dirt collects moisture and your lines still lasted 50 years.
We’re hearing reports of 6 year old cars/trucks with lines bursting from uncontrolled corrosion ... THAT’S A MANUFACTURING DEFECT pure and simple... Should it be caught in an inspection ,, YUP ... Should GM fix safety items like this for a reasonable amount of time for free ,, YUP.
The “copper/nickel” BMW brake lines you mentioned are stainless steel ,, those are the two ingredients you add to steel to make stainless.

LOL, thought about that after I posted inquiring about them. Stainless it is.
Nope. It had thick wall aluminum lines.
Nope. They are copper and nickel. No steel in them.
