I'd call that "the legacy way" or the "C-like pattern". Call it "predominant"
or "established" if you wish.

But The Standard also defines an intuitive, modern, exception-driven error
handling, and I (probably along with every other developer who dislikes leaky
abstractions) really don't see why I shouldn't be using it. Obviously the
transition issues after the inheritance change were foreseeable, so I'd expect
the C++11 standard or any accompanying document to mention it. Or does the
standardization and the resulting guidance deliberately exclude deployment
issues such as this?

Maybe anyone with more insight into the standardization process knows anything
about this?
