One comment on patch-package - just as a follow up for our conversation.
My opinion is that it is not suitable for non bleeding-edge projects and we are not those. Example of where it can't scale us: if we are patching some package and this package happens to be a dependency of a consuming application - we are patching that package for them as well - they do not expect that though...
