If gnu++11 is used, the goal of the authors isn't portable code, is it?
Basically you'd like to 'force' them to use c++11 by taking away the extensions?

I agree

For an app it's easy to depend on another lib. But for a lib,
depending on another lib that might not be easily available /
installable can be problematic.

They could be better but I don't think calling them fundamentally
broken is fair.
