I took the information from: https://www.in-ulm.de/~mascheck/bourne/ and it mentions "modern $@" Maybe at that time, they changed the behavior to become useful. I remember that I was not aware of the specific features of "$@" before 1986 and I am sure that before that time "$@" was not usable as today.
