I would also find this very helpful for doing portable configuration 
management between OS versions.  If the versions can't be listed inline 
in what are already somewhat verbose man pages, perhaps a separate 
feature version matrix could be maintained or generated?

For an example of what this could look like---if it doesn't already 
exist---the Bash Hackers Wiki maintains one for Bash to which I very 
often refer:

<https://wiki.bash-hackers.org/scripting/bashchanges>

Something this useful would be great to show to the systemd-averse, who 
tend to cite instability of systemd's interface as a reason to reject 
it.  Similar portability tables like this are already a great start:

Maybe we can bring back the light.
