This already handled afaict. When I zoom in on apple maps on a stalled data connection I can see the sharp edges of the low resolution vector data until the higher resolution data is downloaded.

On apple maps the app or on the web? Although I suspect that canvas + some homegrown vector engine it is.

The app. I'm not sure how the web interface behaves.
