We don't offer 2x raster tiles because we simply don't have the resources to do it while keeping the tiles minutely updated and open access. We serve around 60k req/sec on a tiny donation backed budget.
The raster tiles are primarily for our OSM mappers to see their map changes rendered quickly to improve the feedback loop.
