I believe it was added for convenience back in the dark ages.  All the
Unix exec functions require a null-terminated argument list (and don't
have an explicit argument count), so argv has naturally always been null
terminated.  (And the C Standard codified that behavior: at program
startup, argv[argc] is required to be null.)
