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

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.
