That's more or less what I'm talking about here. I think the recent revisions have been focused on professionals. But a language's long term growth depends on new people being trained in it to replace the old programmers who are retiring.
I agree, but then again "C++" has no budget to allocate, it depends on contributions from people who are not paid anything to contribute to C++ or companies that are concerned about issues that make their developers more productive. If some billionaire got group of highly talented devs and they worked on a lot of stuff you want(wrote prototypes, wrote nice proposals) I doubt C++ standardization would reject them. But I do not see something like this happening soon.
So I hope I am wrong, but I see very little from your list getting fixed in next 5y(except maybe networking).
