There have been 2 trends over the past few years:

1. the promotion of WASM which is a portable bytecode for sandboxed native code for browsers and other platforms with WASM runtimes
2. the promotion of going away from "unsafe" languages like C and C++

If you're targeting WASM, then "safe" languages just adds overhead on top of the overhead of the sandbox. So C++ can counter the "safe" language propaganda by promoting WASM as a target and saying C++'s value add is that it doesn't add additional overhead on top of the sandbox's overhead.
