I'm just wondering if there's a way to detect if the canvas was made with the purpose of drawing a static image. On providing a better way for those single shot canvases to make sure that the image is preserved, I think one way would be to add a complementing method to toDataURL(), being toBlobURL(). This has the advantage that the Blob URL could act as a cross-origin resource if non-CORS-enabled resources were made to draw the canvas, whereas toDataURL() will just throw a security exception. The Blob URL could still be used to serve an image tag on the page.
