Agreed! I think one of the best parts of the Canvas is that the notes are editable right within the canvas. Since this request has been marked as solved, I would be happy to open a new feature request for the ability to use the Drag note to canvas command to choose either a block using ^^ or a heading using Note-name#Heading-name. Thanks.
Edit: Here is the request: Add editable headings/blocks to Canvas via “Drag to add note from vault” command
