I would presume most (all?) filter.nostr.wine users also have nostr.wine on their relay list so they would still have their full history there.
We could certainly build tools to allow backups but there are already a few good ones out in the wild!

We could also offer an additional relay if there’s interest.
Something like archive.nostr.wine that is slower and has less readers but retains old history.
Seems like a good bridge. Not that anyone would need access to the archives all the time, but every now and then when you want to access that old note, it’s just good to have the options. Seems like that will be the way to maintain balance between memory and speed 🤙💜
