Are there any current NIPs for gossip ideas with Nostr?

I'm wondering about the possibilities of a global view via relay gossip.. i.e. without clients needing to send to ever major relay.. and ideally ideas of every relay not needing to hold all the data. cc nostr:nprofile1qqsgsa449j8ey4ylexnuv8ayrsxyzh88x3dsd4m7nnfcrh96fekvlkspzfmhxue69uhkummnw3ezu7nzvshxweczdw55v ?
