I don't have a preference on the topic but it would still be incomplete, right? There are many other operators that don't have keywords.
Beside the && || ! I think it's much better to not replace the other operators with keywords.
Perhaps that's why not many people use them.
I don't know why people don't use them in C++. Python programmers are usually happy to not use && || !. Maybe they prefer to stick to one single common way to do something.
