I don’t see much advantage to setting up a complex system to automatically keep the forks up to date. In practise, the fork will only need to be updated whenever someone is looking to make a new release in macports from them, so when this happens they can just do this themselves in their own checkout, and manually push it back. In fact, it probably would be better to have this a manual process as it might have to deal with conflicts with whatever patches the fork is using on occasion.
