I've been traveling for the past week but plan on writing up some more 
thorough developer documentation for this including examples of the 
checks added to nova since they don't all follow the same pattern. I 
also plan on starting an etherpad where I will try and go through some 
of the upgrade release notes for the core projects looking for 
candidates so those projects can see what to look for. I know that's 
late for Rocky but should give some ideas for Stein. Feel free to reach 
out to me with any questions though.
