I literally just gave a bunch of reasons as to why.
Evolution of a software and workflows, progress and improvement, relies on being different, thinking outside the box, stretching the boundaries. Copying the industry is the opposite of that, copying and following is backwards thinking, what blender’s workflow is and was, is forward thinking. It came about in the pursuit of a better way, not the way it’s been done before, not a way which is familiar - those things fell aside in pursuit of speed and flow.
Double click adds a layer of ambiguity to the mouse button. Ambiguity is what breaks flow and changes focus from what you’re doing, to how you’re doing it.
