C++ is a bit different in the variety of domains that it's applied to. To expect the same standard library to be useful in games, microcontrollers, medical instruments, aircraft control systems, kernels, and CRUD apps is a huge ask.

Maybe you don't like that, which is fine. But C++ is much broader than what's available in the standard library. C++ is a close second to C in the "how optional is the standard library?" contest.
