Easy to change later, but if we want this, maybe give the existing methods a
dictionary parameter to configure this, rather than potentially adding variants
here? Something like:

any deserializeBuffer(ArrayBuffer buffer, optional
InternalsDeserializeBufferOptions);
ArrayBuffer serializeObject(any obj, optional InternalsSerializeObjectOptions);

We don't have a scenario for configurations - let's do when we have a reason.

Acknowledged.
