Some CTS tests use more than what we expose and other drivers also seem to be exposing many more than us (in the order of thousands). I don't think we want to expose a very large number since we use this limit to size some arrays in the driver, but bumping it a bit over the minimum of 4 required by the spec might be reasonable.
