We definitely need those. Testing a recent version of g++ (or any version of 
clang) in its default 98 mode isn't very useful. We need c++11 at the very 
minimum because without it half of the code isn't tested.

On the other hand, testing all compilers in all modes would be impractical. 
Some sort of a compromise needs to be struck, but I'm not sure how.

The rapid configuration should probably be the latest -std supported by a 
particular version.

This is an undertested configuration so it would probably be nice if it's 
added, even though it's not important in practice.
