Happy new year all 
Just wanted to follow up on the above – I’d like to proceed with those informal “roadmap” and “retrospective” exercises. If you’re interested in participating in either, I’ve branched out to a separate thread so as not to side-track discussion of the DEP process further: Informal roadmap & retrospective workshops for Django.
On the DEP process, if you want to help, I think we could use more “looks good” comments (or objections) on Feature request: allow writing a DEP in Markdown as well as rST #85.
