Hmm ... might be better than not offering them in 8.4 at all, but the
thing is that then you are asking packagers to decide for their
customers which is more important. And I'd bet you anything you want
that in-place upgrade would be their choice.
Also, having such an option would create extra complexity for 8.4-to-8.5
upgrades.
