Good eye, Diego! Pretty sure this has nothing to do with modern keyboards and everything to do with old, serial dumb-terms. Kinda like you never see a physical Meta key anymore, I'd bet if one were to review the devices collected by the various computing museums that you'd find various models without one or more of those keys.
C wasn't widely available for the early microcomputers or minicomputers. Although you can use trigraphs or even change the syntax completely using preprocessor macros, please don't, at least not on code another developer may have to read. Such "alternate syntax" is a maintenance nightmare waiting to happen.
