> The sealed types JEP was already reviewed a while back when we were 
> planning to include it in JDK14. It finally fell off that boat but it is 
> being considered now for JDK15. There have been some changes since then 
> mostly related to subtypes of a sealed type. Before we were planning to 
> infer finality, sealness or non-sealness in the subtypes. We steered 
> away from that direction in favor of explicit declaration at the 
> subtype. I would like to ask for another review of the current version 
> of the JEP that reflects these changes. The JEP is at [1] and the last 
> version of the spec is at [2],
