It occurs to me that it doesn't even need to be a one-size fits all 
solution for providers. All a provider would need to do is have an opt 
in for users to to use selectors who are regularly repudiated, and keep 
the current non-repudiation selectors forever.

If you were to pursue this, what venue would you use? Isn't everything 
shut down?
