Don't understand what your saying here, the OP's question is asking for a part which has been OOP for 6 years, it's a bit like saying car (or any non-bike) manufactures should still be producing their 2007 models on the same production line as a 2017 model, nothing to do with just Shimano, it's the whole world which moves forward.
