Come on, dude. C provides almost no type safety whatsoever. There’s no point in saying “C/C++” here, because you won’t adopt the C++ solutions for making your code actually typesafe.
Type safety is not a standardized term, and it is not binary. Being black and white about things is almost always bad. One needs to weigh and balance a large number of different concerns.
A lot of "modern C++" is terrible, terrible code precisely because of failing to find a balance.
