Yes; but "true" and "false" were intended for use from shell scripts. And exec[lv]p() fell back to the shell if the exec failed, so it even worked from most programs. (I see glibc2 finally implements that fallback; [many versions of] glibc1 didn't, which I considered a bug.)
It should also be remembered that "#!" didn't exist on those systems.
