Is CC-BY-SA 4.0 backwards compatible? Ie. can we reuse CC-BY-SA 4.0 content in CC-BY-SA 3.0 documentation? From my POV, it is important that GNOME documentation is easily reusable in downstream projects, distros, etc., and those often use CC-BY-SA 3.0.
No, CC licenses are not backwards-compatible, only forwards-compatible. If it is a concern for downstream projects, they should probably try to move to newer versions of CC-BY-SA sooner rather than later, as it solves other problems such as making attribution easier and adding a 30-day window for license violation corrections. For the moment, it probably makes sense to stick with 3.0 to ease reuse.
