Linux has a lot more inertia than a smaller project such as u-boot.

Code seems to flow from Linux to u-boot more than the reverse -- I don't 
see much of a problem with being more permissive.

I suspect that has more to do with people's feelings toward C++ than any 
  unbiased assessment of the merits of the features.
