I just read the following paper: "Massively Parallel Rendering of
Complex Closed-Form Implicit Surfaces"
https://www.mattkeeter.com/research/mpr/

While it's not geared for ray tracing as is, I'm wondering if this method could
be used to add a pre-trace subdivision step as already exists for parametric
surfaces.

The most interesting aspect of the algorithm "tape shortening" which
automatically simplifies the function for the various segments. This seems to
work well for CSG heavy functions (min, max operations).

Or does Pov-Ray already do something along those lines?
