Hands on - I tried to switch some workstations to CS8 like it would be
done at the end of the year. The next monday would bring me angry users
into my "virtual" office because there applications does not run
anymore. What happens?
Applications from 3rd party repos like RPM Fusion that link against
"qt5-qtbase(x86-64) = 5.12.5" do not have any providers anymore
(CS8 got an upgrade to 5.15.2. So, like EPEL it seems that
everything else needs also a -next branch (just kidding).
What would be new in 8.6? That will be state of CS8 at the end
of the year?

I expect that such upgrades will happen in RHEL productions phase.
When this phase ends then CS8 is also EOL, and that point would be
the only dist upgrade situation where no surprises would happen ...

The bottom line here is that a slightly more complex setup/configuration
of a system would lead into a higher risk that the mentioned upgrade
path would fail. Complex means here every things that uses more then
just CentOS artifacts (ISV/proprietary software, 3rd/custom repos,
etc.). As mentioned elsewhere because RHEL has stripped a lot of
packages out of the compose, people are forced to compensate this with 
there own builds, what leads to the above mentioned system
