Agreed. What I have been able to look until now was the high-level structure of the patch, and I think that we should really shave 0002 and simplify it to get a core infrastructure in place, but the core patch is at another level, and it would be good to get some feedback regarding the structure of the patch and if it is moving in the good direction is good or not. -- Michael
