Oh, I'm so sorry for replying this late, the team made me aware but I complete forgot! In short, while I think of course that this is a fabulous idea, it's quite hard to put into practice. I would have to start by creating an embeddable version of the map, generate URLs for those and than it still depends on the other frontends whether they would support that URL or not. So while not impossible, it's largely impractical (and also would be expensive for me with so many google maps instances I think)!

In short, I think it's a very cool idea, but I think it's highly unlikely to become reality! I hope that answers your question somewhat?

However, an easier solution might be to get frontends to show a little map in the post if the Pinmapple code is there (that way no embed is needed which makes things a lot easier and a link to the bigger map can be added too). This would be miles easier and the little Pinmapple code holds all the info needed for any frontend to implement this. If this would be brought up with frontends I would obviously 100% support that!
