If we want anything in between we likely need a new store. Allocating that on existing users' nodes would be problematic. We can't get rid of the pubkey store just yet. Using CHK slots to store smaller keys would be rather sad. Subdividing them would be problematic as one CHK would evict many smaller keys, and do we really want one smaller key to evict one CHK? It looks like this would be fine for FLIP. But FMS/Freetalk probably want something medium sized, like 2KB or 4KB?
