I just realized it is actually a bit easier than that to go from a post’s home instance URL to one of the foreign instance’s URLs - search works for that. Eg, if I search for https://lemmy.ml/post/175984 on lemmygrad I find https://lemmygrad.ml/post/131812. However, search doesn’t work for finding the original URL if I only know the post’s URL on a federated instance.
