Note that `sealed` already has a meaning in the context of packages (see Package.isSealed()), though it is minor. Is there a different hyphenation of final other than semi-final that maintains the connection to finality, but doesn’t weird people out? (One thing I dislike about sealed / non-sealed is that now we have _contextual_ keywords with hyphens, which wasn’t the discipline we were aiming for in the hyphenation proposal.)
