I'm working through the last few open bitcoind/btcd methods, pertaining to network management and diagnostics. @josie has the three Sparrow SP methods, and @eynhaender is enabling some partial mempool method support for client compat. These will truly close out the last WIP client-server methods for v4. Everything else is either rejected (not much of this), partial/pending v5 mempool, or complete.
