I think this is a fantastic approach and well worth doing. One thing that would improve it IMO would be to use a "Header: value" style more similar to robots.txt, though;
So for instance, instead of
[upstream]
krystal.co.uk
it'd use something like
[upstream]
Domain: krystal.co.uk
Or other kinds of identifier:
[upstream]
Name: Ecotricity Group Ltd
This gives more room for extensibility in future, where new forms of addressing or relationships can be supported.
