Agreed, but it could have been there since day one, given the languages in 1960's.

Well, Microsoft has considered C done for quite some time, and after C++20, they don't seem to be in a hurry to keep up with ISO either for C or C++ (there are discussions on support channels about customer relevant C++23 and C++26 features, none on C past C17), similar to how Apple and Google are handling their in box compilers as well.
