Right, I sympathize with this concern, but as the debug callback is defined to
only have one data pointer and one data type, I think it is better to adjust
to this now and then possibly introduce an enhanced debug callback
funcionality in the future that wouldn't split the info in two parts.

I don't want the app to be needing to split the data into a text part and a
data part.

Yes that's what I mean.

I think that would be a very good approach. A textual description for the
(possibly) binary data. That would require a new curl_debug_callback indeed.
(It would also nicely address the 3rd-party which-host output problem.)
