Web_view for the C++ Standard Library (open-std.org)

This seems like a pretty far reach from what's otherwise in the C++ stdlib. Also, the field is quite complicated and still changing -> to me this seems like something that would be interesting to have, but a) I don't think the standard library is the right place for it and b) it would really only make sense if there is access to multiple engines through it, something I don't have the impression the browser vendors care for.
