You are totally right of course. Doing that wholesale switchover and  
replacement simply wasn't something I could get done for 2.2.0. I  
thought about that many times as I went through all the places that do  
define actions. Actually there's not two, but three different  
machineries in play when you consider the workflow actions, and those  
workflow actions are the strangest because they don't use TAL  
expressions but string replacement to expand the expression-style

Yes, there's redundant information in many places. Collecting all  
actions in the actions tool itself would be the cleanest way, but a  
more manageable first step would be making type information objects  
into action containers as you suggest. The same could be applied to  
DCWorkflow Worklist and Transition definitions.

I have added a Launchpad "blueprint":


Collecting our projects as blueprints has the advantage that there's a  
single place to track all of them, with concise information about the  
task and who's doing/reviewing it:
