Yes.

No. On C++98, std::list is required to have O(1) splice(), in C++11+, O(1) 
size() instead. The two are mutually exclusive, so std::list cannot be BC. And 
at some point GCC will (have to change|will have changed) its basic_string 
implementation to not be CoW anymore.

And all of this will still be true. Except that - like every other C++ library 
- distributions need to deal with the incompatibility of std::list and 
std::basic_string between C++98 and C++11.

Thanks,
