I start wondering if it is possible to wrap the STL containers in Qt6 and give them a nice, intuitive, Qt-like API while still providing full STL compatibility. I am sure this has been evaluated. Are the results documented somewhere?
I've done this experiment for QMap / QHash / QSet, where keeping COW at the cost of an extra indirection (dptr -> [refcount + std:: class] -> actual data) is more acceptable since these classes jump all over the memory anyhow. Basically "it worked", still requiring a few changes though, e.g. std::unordered_map iterators are forward, QHash ones are bidirectional. If the SIC is acceptable, something to consider for Qt 6.
