You can manually bound, if you use '-ur' / 'remove_bounds=off'.
The '-b' option turns off all general object bounding(*) in the yuqk
fork. It turns off most, but not all, of that same general bounding in
v3.7 and v3.8 versions of POV-Ray.

(*) - Bounding methods 1 (slab) and 2 (bsp).
Beyond that bounding, some shapes like blob{} and mesh{} / mesh2{} have
internal bounding which can sometimes (always?) be turned off with the
SDL 'hierarchy off' object modifier; Some shapes - like the sor{} - have
internal bounding that is always there; Some shapes always use a
contained_by{} shape which both determines bounds and can become part of
the overall result - a little like a, tucked in the shape,
intersection{}.
