Move normalize args and recursive visit into the existing normalize delegate passed to schemas. Custom Schema.normalize() implementations should migrate from normalize(input, parent, key, args, visit, delegate, parentEntity?) to normalize(input, parent, key, delegate, parentEntity?), then read delegate.args and call delegate.visit() for recursive normalization.

Before:

class WrapperSchema {
  normalize(input, parent, key, args, visit, delegate) {
    const normalized = visit(this.schema, input.value, input, 'value', args);
    delegate.mergeEntity(this, this.pk(input, parent, key, args), normalized);
    return normalized;
  }
}

After:

class WrapperSchema {
  normalize(input, parent, key, delegate) {
    const { args, visit } = delegate;
    const normalized = visit(this.schema, input.value, input, 'value');
    delegate.mergeEntity(this, this.pk(input, parent, key, args), normalized);
    return normalized;
  }
}
