I agree that there are many similarities with instance mode. I learned about it recently but at first it seems a little mystical. Moreover, it seems to be a little bit of a secret. For example, the reference for createCanvas says “If you want more than one drawing canvas you could use [createGraphics] …” But the createGraphics technique doesn’t really give multiple canvases which part of the reason I started this project. At least for people who have used named DOM elements, I think that MyCanvas technique is easier to understand.
