Yes, this is kind of stupid.

Certain people have been doing this sort of thing forever. It was never a good idea. Whenever you probe why they thought it was a good idea, all the reasons (where they are expressible at all) turn out to depend on falsehoods. Most usually, though, it amounts to laziness about learning anything new.

You can see effective use of Modern C++ in SerenityOS, to excellent effect.

So it is basically Modern C++, just a few years later.

It's 2022, so perhaps the committee will approve features from C++17.

Now, all things considered, having used bgfx in various languages, I think the Orthodox C++ approach leads to quite clean code.

It reminds me of Carmack's subset of C++. In other words, it doesn't suck.
