But once there is a event, another app can keep the events for longer 🫠 

 The logical conclusion seems to be that there is no solution. 

 Could you guys help me create a NIP? I’ve written a more detailed post. I might be naive, but I believe we can create something that resembles a temporary event. I am going open a PR but I'll need help (I hope to not feel ashamed haha)

 It already exists. It's NIP 40 https://github.com/nostr-protocol/nips/blob/master/40.md 

 It's no way close to that nostr:nprofile1qqsyvrp9u6p0mfur9dfdru3d853tx9mdjuhkphxuxgfwmryja7zsvhqppemhxue69uhkummn9ekx7mp0qythwumn8ghj7anfw3hhytnwdaehgu339e3k7mf0qyghwumn8ghj7mn0wd68ytnhd9hx2tch2deau 

 Why? Just do an `expiration` tag with now + 1 second and boom the event is gone before its even downloaded from the relay.
