Wolfgang, you know me long enough to realize that this argument is
*crap*.

Talking about business cases, it has turned out to be extremely
difficult to explain customers that the effort for the actual
functionality is only a little percentage of the work necessary to do
the oftree stuff right. The functionality has often worked after a few
hours, and until all oftrees have been solved, it often takes weeks.

In result, this has already led to customers concluding that

- mainline is not worth the effort
- linux is overkill and one should better use cortex-bare-metal

However, that is only our personal observation.
