Well, it's also necessary to know the redirect target if you're using the Finder to access the OSS from Snow Leopard.

The number of people who are affected by this bug ≥ the number of people who are affected by this bug and won't know what to do if you move them to a different machine. I'll ask my question again: if someone calls in with a problem for which the solution is to provide them the current redirect target for their account, and the support ninja gives them that information, are you going to a) never migrate them to a different server, or b) contact them when you do? If neither, then your concern about someone getting this same information from the website instead of a support ninja is unjustified, because they'll be equally out of luck.
