Comment 10 for bug 1482786

My train of thought is that the setgid bit isn't inherently necessary to make cat files work - it was added before my time as maintainer with an unsatisfying explanation, and I've long been intending to look into it properly - and the cron job was there to work around a problem that was never fully diagnosed. IOW, neither of these issues are central to cat files. I plan to pare these things away, but I need to do some auditing to make sure that I'm not going to break anything else in the process.
