This sort of thing makes the lack of a downgrade process a real problem. If you rely on something that uses Rosetta, you aren't likely to find out until after you've upgraded, at which point it's too late, you're stuck with it and lose that app. Which means that if you _don't know_ whether you're relying on Rosetta (which most people won't), upgrading is a risky proposition, which people will want to avoid.
