I am not opposed to doing this but I think that the patch is way too big. At the momment we still have issues with the last "big 
patch" that are not cleared up [1]. On the whole unless we cannot avoid it I really do not think that we should be making such large 
changes in one go like this. Please break up the patch into smaller patches. That way it is easier to find and fix any issues that 
arise.

[1] New versions end up as orphans with current setup.
