To be fair, Googlers can't write modern C++ because they have a critical mass of legacy code that has never been exception-safe. Avoiding RAII kneecaps the whole language badly.
The beauty of RAII is that every resource is tied to the lifetime of an object, and every object is always in a usable state. Having to call extra open/close methods and check error codes breaks these invariants, and leads to objects with bad fidelity to the normal copy and move semantics the language is built on.
