Like anything in engineering and design, IMO, it depends on who you are what you are doing.

Why convert a SDF to a mesh to do visualization and engineering analysis? Even with FDM, which can be thought of a 2D filling problem like scan conversion once you have a SDF, meshless may be the way forward with additive manufacturing as well. One can think of reasons you would have to do mesh extraction, but for niche areas of manufacturing.

True for FDM, but for SLA you have the potential rendering a direct slice of the SDF.
