I think I just found out the hard way that the min_extent calculation
for blobs calculates the furthest extent of any component, and not the
surface which is "raytraced" and controlled by the threshold.

It's not really a calculation, it just returns the corners of the automatic
bounding box. The bounding box isn't always the smallest one possible in
complex situations like CSG and blobs; I suppose that should be documented
somewhere.

Fair enough.
If I go to the trouble to write my own code with the trace function, will I hit
the bounding box or the raytrace-able surface?

trace() checks against the object so no problems there.
