Removal of these options from ProtocolConfiguration is scheduled for May-June
2023 (~0.103.0 release).
## GetPeers RPC server response type changes and RPC client support
GetPeers RPC command returns a list of Peers where the port type has changed from
string to uint16 to match C#. The RPC client currently supports unmarshalling both
formats.
Removal of Peer unmarshalling with string based ports is scheduled for ~September 2023
(~0.105.0 release).
