A bit of a tangent but.... AFAICT, /var/log/messages has been 0600 root:root
for quite a while.  So it's more correct to talk about how changes have
opened up /var/log/messages to a group than how it's closed off a world
readable file.  Do your fresh installs show something different?

If so... usually people want to look at doing as a superset of seeing.  We
talk about read-only vs read-write a lot more than read-only vs write-only.
