IMHO using different codes is more important than using different 
interfaces since the usual pattern is just to check e.code in the handler. 
Having to check e.code and the interface type makes things twice as 
complicated.

Having to make sure all the spec writers for Web platform specs 
communicate is *not a bug*. It's absolutely imperative not just for making 
sure exception codes don't overlap (something that really hasn't been much 
of a problem in practice since we have a de-facto registry that we use for 
the purpose) but simply for making sure the platform remains sane! I think 
it would be a mistake to make it easier for Web platform spec writers to 
isolate themselves from the rest of the ecosystem.
