In fairness, the command-line world of the BSDs of the 1980s is long gone in some respects, and this is not just some Apple/NeXT idiosyncrasy. OpenBSD's ftp command has become a generic multiple-protocol file transfer tool, different to the ftp commands of the other BSDs. (FreeBSD puts this functionality into a tool named fetch, instead.) The r- commands were eliminated from FreeBSD some time ago, with much the same happening to them as happened with telnet on MacOS. They are no longer in the operating system, but are applications that one can install from packages/ports. BSD re-vamped its command-line interface to ps in 1990. It has been getopt-based, and documented as such, for 29 years and 7 days. rc.local was labelled obsolete in FreeBSD in 1995, and deleted from base in 1998. And so on.
