The powers that be have spoken, and no change has been made.
The English patch of Rosenkreuzstilette will require the game disc, physical or ISO.
This decision will most like not be changed at all, as it is the best possible method is terms of quote "practicality and ethics." This, in turn, means that you will be left to find the game image or disc on your own. For those of you who already have the game installed, you will inevitably have to uninstall the game and reinstall it from the disc using the English patch. Replays are transferable, so you'll probably want to grab those before you delete it.
For anyone who does not have access to the game disc for any reason, I'm sorry to say that you're pretty much left out. There's nothing I can do about this decision, so there's nothing more that I can say.
