"dead end" as in "too hard to implement"? Or for some other reason?

It's undeniable that auto-retry would be better from a user's
perspective than a user-visible cancel. So if it's *reasonable* to
implement, I think we should be working on it. I'm also very puzzled as
to why nobody else wants to even discuss it; it's like some wierd blackout.
