are there
other tangible[1] manifestations of non-UNIX operating
system things like the GECOS field that were carried forward intact in
later UNIX implementations?
Job control was inspired by ITS job control capabilities. Control-Z
does pretty much the same thing in both operating systems.

I don't think
"carried forward" describes job control, which I
believe was never in any Research system. "Borrowed" would be
more accurate. In fact, I don't recall being aware of the
existence of the ITS
movement at the time Unix arose.
Was there ever a movement? It was just four machines at MIT.

I struggled over the word when I wrote it. ITS has been described
as some kind of pushback against the big (and ostensibly commerce-
oriented) Multics project. I still haven't though of a word with
really appropriate connotations.
