Sorry for the noise then. I assumed that if everybody starts sending potential patches to stable without them being the accepted ones, you will end up having to deal with a lot more workload that you already have. And just to be sure that there is no misinterpretation, I did not wanted to imply that stable was not smart enough to deal with such patches... I really appreciate the work done and my concern was to not add workload.
