No such strategy is necessary. That discourse was about not using C++ for applications where Java would work just as well.
The US government still uses C++ widely for new projects. For some types of applications it is actually the language of choice and will remain so for the foreseeable future.

Can you give an example please? And how does it correspond to government ONCD report and other government docs "recommending" "safe" languages like: Rust (noted for its ability to prevent memory-unsafe code), Go, Java, Swift, C#, Ruby, Ada
Among other things I design and implement high performance C++ backends. for some I got SOCS2 Type II certification but I am curious about future. Do not give a flying fuck about what the criteria for military projects as I would not ever touch one even if given a chance.
