I realized how far my tangent went after I clicked 'Reply.' I think the answer to your question is yes, there are people who would want that, and decent arguments not to provide it (eventually it will be a service offered somewhere anyway though.)

I'm not one who is against such tradeoffs on principle necessarily, but do encourage corresponding education (transparency) of the actual tradeoffs - in other words customer ought have a way to learn about the decision from a maximally paranoid security perspective if they so choose - and would want that to be up front from the provider.

The model I think of that's closest to the ideal tradeoff would involve distributed trust, i.e. 3 people I trust can get me back my nsec but no one of them has the whole thing.

I went on another tangent. Twas fun tho :D
