Thanks for reply, but many of the libraries exist in boost, after some years candidate for adding to C++ ISO, so I think if we migrate iostream to latest standard of C++, we can candidate this library for ISO, because this library is very helpful, and general as standard wants.

Lots of people use boost because they cannot use C++20 or even C++17.
For those users, boost provides C++11 or C++14 portable equivalent of
new std libs (boost::optional, boost::variant, boost::filesystem, etc.)

If boost required C++20, many users would not be able to use boost anymore.
Boost should be not require such a recent C++ standard. C++11 or C++14
are probably the best minimal standard for Boost IMO at the moment.

Furthermore, looking at https://en.cppreference.com/w/cpp/20 (core language
+ STL), recent versions of gcc or msvc are in good shape with C++20 but clang
is less complete.
