I don't recall Cortado having any support for seeking if the server
doesn't support byte-range requests, as in this case.

I think the proposed use case is essentially to permit client-side-only,
backwards-only seeking when accessing servers that do not support
byte-range requests.  It seems to me that implementing such a feature
might be possible, and David is on a somewhat reasonable track, although
oggz_chop[1] would be much easier.  Oggz_chop controls will also be
necessary anyway for forward seeking, so implementing the caching first
seems like premature optimization.

To make local-cache seeking work, I would recommend following the seek
event model used in gstreamer [2], as Cortado is essentially a clone of
gstreamer.
