some of the STL is easy to improve on. For example, std::unordered_map performs poorly due to pointer stability requirements in the standard. Most performance sensitive C++ codebases will use something like abseil's hash maps instead.

to more performant runtimes and architectures in response to operational concerns at scale, which have a tenuous link to language

The runtime performance and the language are deeply linked. None of the dynamically typed runtimes you mention are actually performance competitive with JVM languages.
