Imagine how widespread use of Java 8, .NET Framework, Python 2, C89 is still around the industry and now apply it to C++ versions.

There is a reason why C++17 is the best we can currently hope for in what concerns portable code, given the actual support across industry compilers, and company project guidelines.

Many embedded shops might still be discussing between adopting C++11 or C++14.

I agree, but there's a big difference between saying some industries or companies are still targeting old standards and saying there's "near zero" adoption of new standards. The latter just isn't accurate from what I see.
