I'm thinking something like:

start loading VE
done loading VE UI
start rendering VE content
done rendering VE content
done loading VE

These would make it easier for other scripts to hook into what is going on. We could use it for instance to add the BLP/disambig editnotice to the actual edit notices on the english wikipedia. https://en.wikipedia.org/wiki/Wikipedia:Editnotice#Edit_intros
