The correct response? Yes. What should be the driving force of Jon's story? No.
Issue 9 had potential, but it was packing about a story arcs worth of ideas into rushed narration that was already truncated by a rather pointless fantasy. As it stands, it's rushed and nothing your suggesting about danger Jon was facing really came across. And again, the aging up is erroneous there. You don't need to age 7 years to have a coming of age moment. In fact, I'd argue if you need a character to age 7 years to have a coming of age moment, you're not really having a coming of age moment, you're cutting corners.
Personally, it's irrelevant to me. Even if Bendis tells the best stories with Jon in the world (which I'm not optimistic about), we, as fans, were still robbed of watching him grow up and reach all those milestones Bendis just glossed over. It's a sucky way to treat a character, especially one who was already the center of a beloved series. I have never personally been more frustrated and disappointed with a choice made by DC comics. And I'm a Wally West fan.
