@memimo , this is going to be your CCW task. I don't know what's need to be done yet, I just summarize information.

I list here the issues with some summary because the title doesn't always correspond to the discussion.
I found several discussions on initialization:

• Initializable _push_initialization_config #773 where many people are complaining about the current way of initialization and pushing the config
• Better configuration of initialization #740 which proposes a new way to initialize stuff
• Initialization discussion #384 another thread on initialization
• Lazy Initialization: Discussion #31 and yet another

Other threads which concern initialization:

• Check whether all bricks were initialized #347 discussion on where we should check if every brick was initialized
• Better Printing of Initialization Schemes #463 enhance initialization schemes printing
• Should Sequence be Initializable? #816 argues about noninitializable sequence and raises a question how we should manage several different properties
• Multiple parents blow away child bricks' existing allocation #935 figures out that allocation and possibly initialization is broken with several parent bricks

@rizar , I forgot something?
