      We currently treat page discards as a full page write of a tombstone, but we should instead treat it more like a delta write.

      The Server team has requested that we set the LSNs for a tombstone write accordingly:

      • base_lsn = the LSN of the last full page
      • backlink_lsn = the LSN of the last page version

      Note that this would require us to store base_lsn in the address cookie, so that this information would be available for fast truncate as explained in WT-14960.
