Lewis, I am not into astrophoto yet.
I have read many, many reviews and non mentioned soft focus. They did say, there was a slight hint of ca and the focuser isn't exactly first class but still good enough to use.
You yourself say it is subjective so I will go with these reviews, not your subjective comment, as these numerous reviews could not be wrong.
As for the comment that today there are two type of glass used in the ED127, where is the proof? Sound more like someone fertile imagination.
So more myth than fact!
