I think that's the key point, the scale in which this starts happening is the sizes of the Googles and Facebooks of the world (in C++: Abseil and Folly) but also in Java (at Google: Guava), JavaScript (at Google: closure, Angular/Polymer/Lit/and many others).

So people extrapolating from a ~100 person company or a ~1000 person company using JS might as well think it's about the language, but it's really about the size, I think.
