Thanks for trying to explain this to us.

You are insisting here on talking about the "handle" part, though isn't the crucial part of the complete chain weather we use either did:web or did:plc?

So as you outlined yourself in the article. If you a) use did:web b) ever loose access to that domain you are cooked. No amount of handle changes can help here. If one looses a handle domain one can loose a did:web domain also, so that just moved the problem to a more opaque place.

So your identity is always either a) attached to a domain you might loose b) to some plc provider that might stop work for you.

Please correct me if i get anything wrong here, as that is just how i understand it.
