Well, to get the ball rolling a bit, the key thing that matplotlib needs to know is if `shape`, `reshape`, 'size', broadcasting, and logical indexing is respected. So, I see three possible abc's here: one for attribute access (things like `shape` and `size`) and another for shape manipulations (broadcasting and reshape, and assignment to .shape). And then a third abc for indexing support, although, I am not sure how that could get implemented...
