Document exclusion lists facilitating deletion about handbook HOT 3 CLOSED

Yeh, this is actually separate thing from the exclusion list (although that triggered the line of thought). A deletion list would only ever be kept locally, never broadcast (it could get massive sometimes).

That's a nice description of a deletion protocol!

I understand exclusion lists as a manual configuration by node maintainers so I'd be surprised to suddenly see my configuration automatically being changed without my consent but if we keep track of that internally, on top of these configurations then it's all good, just want to separate the concerns.

I see I confused terms in there, will fix that.
