So really the issue is with the engineering and not with the use, or lack of use, of an oil analysis.
So fine, if you buy a E46 M3, Z4M, or even a E9X M series you can use oil analysis to figure out when the rod bearings will bite the dust.
But for 99.999% of owners, an oil analysis is not necessary, even if you are a BMW enthusiast and think it's cool to have your oil tested in your-over maintained BMW.
Warranty does have to do with it, because track use is generally not covered and is considered excessive use that voids the factory warranty. So if you buy a new car and then track it, an oil analysis may tell you the engine is experiencing undue wear on internal, oil-lubricated parts. But the end result is the same, the manufacturer will not cover engine damage due to track use.

Where did you take the information that track use is not covered under warranty?
