I can see the converse argument to make the DataStream API use DTMF if it is the only thing available, in order to avoid adding a DTMF-specific API, but I think the semantics are different enough that the DTMF API is a better approach. Regarding whether this API should be extended to be a generic codec API, I think it should be obvious that the ability to send one of 12 well-defined signals in a standardized manner is orders of magnitude simpler than the configuration options available for modern video codecs.
