Thats quite true!
Back in the days of 3b2 300/310/400, Tar is (was) only on a 3B2 if you
had a Tape Streamer (the old 23 Mb one) - theory being - all software
was supplied on "floppy's with files systems." CPIO was used to "pass"
the info onto the AT+T. You got "tar" as part of the "Cartridge Tape
Utilities" floppy.
Maybe part of the campaign to oust "tar" and bring in "cpio". Who
cares - I use "afio". (Did anyone fix the cpio -ic Bug ???
("Portable" ascii headers) - when restoring files with numeric file
names (eg /usr/lib/terminfo) - You sometimes get "End of Media"...)
