Currently, our streaming overloads (operator<<) make use of io manipulators. This means any ostreams making use of such overloads are also required to implement IO manipulators -- this adds non-trivial complexity and state. Not only that, they are cumbersome to use, and typically require saving existing state and restoring it with an RAII object -- this is often forgotten, as is the case in our codebase.
The replacment is built on top of C++20's std::format.
