Applying filter to a non primitive property still creates an empty collection on the client

[WesleyClements]

The code I have is something along the lines of

class SubSchema extends Schema {...}
class State extends Schema {
  constructor() {
    super();
    this.activePlayerIndex = 0;
    this.playerIds= new ArraySchema("1", "2", "3");
    this.playerState= new SubSchema ({ a: 1, b: 2, c: 3);
  }
}

const types = {
  activePlayerIndex : 'number',
  playerIds: ['string'],
  playerState: SubSchema,
};
defineTypes(GameState, types);

filter(function() { return false; })(State.prototype, "activePlayerIndex");
filter(function() { return false; })(State.prototype, "playerIds");
filter(function() { return false; })(State.prototype, "playerState");

I'm expecting that the state on the client to be something like

{}

but instead I'm getting

{
  playerIds: [],
  playerState: {}
}

From everything I can find, it seems like I'm using everything properly but you'll have to let me know.
I would like to hide the property names in addition to the elements of the collection.
I see the value in restricting info about the server implementation specifics.
I could achieve this by not annotating types for those properties but that restricts the usefulness of any presence in use.
After looking into this, it may just be a result of the schema serialization not taking filters into account.
This might be fixed by adding an annotation like @internal to notate fields that are only meant for the server.
