One of the issues I have with such classes is that they make other tools
for finding bugs, like sanitizers and valgrind, useless.

This code is racy, even with the internal mutex:

if(container.empty()){
   container.insert(....)
}


but since the data is protected by mutexes and synchronized, not tools
will complain (AFAIK).

Thus even if such class would be standardized, in most cases it is
useless/it is a not a good primitive for multi-threaded code.
