Is this still possible since the package version changed and this was the last field? I think if it is attempted to be used, the codec would fail on an unknown field?

It may be useful to reserve these fields. cc. @colin-axner

Make sense to me. Would this still be a concern if we shifted all the field numbers?

is this the usage you had in mind @damiannolan

message Misbehaviour {
  option (gogoproto.goproto_getters) = false;

  uint64           sequence      = 2;

hmm, perhaps we should just shift all the field numbers considering its going to be API breaking anyways and require migrations. I think its probably safe to shift them then. Any thoughts or reservations on doing that?

I think it should be fine. I don't see any security considerations since this is for providing misbehavior and it isn't stored within the state machine (no internal migrations are actually needed for this type)

uint64 sequence = 2;
SignatureAndData signature_one = 3 [(gogoproto.moretags) = "yaml:\"signature_one\""];
SignatureAndData signature_two = 4 [(gogoproto.moretags) = "yaml:\"signature_two\""];
