No, Remi, there is no SCCS view, because RCS is superior.

RCS uses backward deltas, as any reasonable versioning
scheme must, because deriving the current version of
a file must be faster than deriving a historic version.
SCCS is wrong-headedly out of step with history,
because it uses forward deltas, and thus requires
the CPU-wasting recapitulation of the entire history
of a file in order to materialize its most recent version.

Thus, SCCS is almost as dumb as a loser-system which
which would store bit-images of *every* version of a file,
and then (magically, as if it were possible) would retrieve
those bit images on demand by some sort of magic
name.  Hah, as if one could build some sort of
interplanetary file system (they’d call it “IPFS”,
the losers) that just shared files by *wishing*
for them!

P.S.  I once wrote an SCCS ingester in Java,
when HotSpot was stored in SCCS.  I lost it.
True facts, those.
