I think you're right that some things, such as integer addition, are quick and don't require a lot of thought, but a lot of teams leaning to C++ stems from larger-scale performance considerations that aren't one-size-fits-all. A simple example is `std::vector`. The structure is a nice resizable array, but for a long time you couldn't override the allocator and the performance of your application could be affected by heap fragmentation or even just the performance cost of heap allocations. A lot of C++ shops often wrote their own replacement containers that had a better allocation strategy. The design needs of a PlayStation 2 programmer ended up being different than an x86 desktop computer with virtual memory.
