Contrary to Graham Kings' repeated assertion (scroll down to the first long comment here, the Proposed Anglican Communion Covenant is not "the only way forward." It is one of many ways sideways.
The Proposed Anglican Covenant (Part 4) attempts to manage disagreements by assigning a supervisory task to the Standing Committee of the Communion, and the power to make recommendations not terribly unlike what can now be done without a recommendation, but simply by each province on its own to refuse to have to do with innovations elsewhere that it doesn't like.
Surely this is not the only way to manage disagreements, nor even the best. The simplest way, Gamaliel's laissez faire and provinces ignoring what they don't like in other provinces (as they are free to do, and have done) seems much more likely both to keep some relative peace and lead to eventual reform or reception.
There is no need to manage disagreement. People can be quite disagreeable on their own.
