One of the reasons people volunteer in open source projects is to scratch their personal itch. When that itch develops into a festering, gangrenous limb it becomes time to amputate it. That is what I am doing with my involvement in x11-drivers/nvidia-drivers. As a result someone will need to work with spock and rej to figure out what aspects they are able to maintain and then maintain the components they aren't able to. For example, different hardware has different series of drivers to support it.
