If container is passed across a library boundary, there is a question what version of new/delete should be used. But this can be "easily" solved by providing allocators. Probably.
> Binary compatibility of stdlib is not an issue So, you think that this is easy to achieve binary compatibility with many C++ compilers and standard libraries we have? For example, if Qt is built with one version of MSVC, but used in a program build with another version of MSVC. This is nice if there are some guarantees at least for main platforms. I heard that gcc and clang give some guarantees, but this not enough, I think. > consistency for containers shouldn't really be either Regarding consistency, it's not only containers' implementation. This is also about Qt APIs consistency: if it will be decided using std::* containers, they should be used instead of all Qt containers, but not instead of some of them. I guess, we should provide more or less solid user experience.
