@kevin One that is actually usable? Yes. The share link can only work on your own instance and there's no way to know what that is. I would love to be proven wrong but I can't see how to build such a thing that isn't just a giant pain in the ass.
@mcv indeed. there's a generic protocol in the works for "sharing" as well: https://github.com/mgiuca/web-share/blob/master/docs/explainer.md
