Hmmm, again, I feel like this might be just me being too picky, so feel free to disagree, but I feel that the wine is something exclusive to a Passover Haggadah. You would never find wine stains on an old Psalms, for example. Tear stains, certainly. Even blood, in some extreme cases. But not wine.
Perhaps you should ask what the rest of the community thinks about it whenever you end up doing that meta post.
