I think no; the VeryLow that it gets by default is probably correct.  Priority in WebKit loading only controls when requests are sent to the network layer (the lower the priority, the later they go out), and for prerender being late like a prefetch is probably correct; the prerender fetch then won't interfere as much with main resource loading.  In the subresource case, the contrast is that the resource is associated with the current page, and Low priority mirrors what something like an image would get.
