Only issue I see with auto generating a note when you create a [[…]] link, is that I find myself typing one thing for the link name and then realizing I want something else. And often I decide to add an alias so the sentence in the note makes sense and the new standalone note name makes sense.
Therefore, if there was an auto generated note feature, there would likely need to be a Delay aspect. Maybe even hours or a day delay if desired, or on next start up.
