BSD is the new kind on the block. I don't think it came along until 1977 or
so. Research UNIX I don't think picked up SCCS ever. SCCS first appeared in
the PWB releases, if you don't count the earlier version in SNOBOL4 for the
IBM mainframes.

Email was internal to the system. Email between machines came along later.
Also, I don't think we ever used the word "commit." Actually, much of my
early work predated the introduction of SCCS. ;-)
I should have been more clear. The Unix history Git repository contains
synthetic commits imported from snapshots, patches, SCCS, CVS, and Git
files. I took the liberty of attaching the email ID(a)research.uucp on all
Bell Labs commits, even though many predate UUCP email.
Your SCCS work belongs to the mysterious subset of Bell Labs commands that
made their first public appearance on BSD Unix. I didn't find SCCS included
in the 6th or 7th Research Edition, nor in Unix 32/V, which, I understand,
were the ancestors of BSD.
Specifically, I first find SCCS included in the BSD-4 snapshot (e.g.
usr.bin/sccs/sccs.c) and also in the BSD SCCS repositories predating BSD-4,
through commits such as the following.

changed path to SCCS/s.
added chghist & help
generalized argument chomping
SCCS-vsn: 1.2
Other commands that fall into this category include fsck (frodo), gres
(lem), efl (sif), diction (llc), and ideal (cvw). Somebody has commented on
this list that a secret tunnel linked Murray Hill and Berkeley. I'd welcome
any better explanations you may have.
I'll find a way to graft you as the developer of SCCS somewhere between
BSD3 and BSD4, so please do claim marc(a)research.uucp on GitHub. Are
there other files I should also attribute to you?
