You can throw a voxel remesh modifier onto your model in Blender to get the same functionality. It will convert your model from polygons to SDF and then back to polygons.
I would imagine that's a fairly lossy process with some downsides?
Ideally - the end result of an SDF pipeline is pixels. Going back to polygons throws away much of the advantage of SDFs. Raymarching is costly and rarely used in realtime engines but Blender isn't realtime so rendering SDFs directly would probably be viable.
It's a lot easier to handle realtime in an editor than in a fully featured game. There's less other stuff going on, you can take extra shortcuts and usually rely on higher-end hardware.

I don't think that's true. Most games are optimized to limit the number of draw calls and textures. The viewport of a 3D software package has no such limits. As a result, my viewport rarely runs as well as the games I play.
In any case, that's besides the original point, which was that it wouldn't need to run in realtime. My argument was that it would.
It's not a completely impossible goal. Look into what some artists are making with Dreams on the PS4. It uses raymarched SDFs for modeling.
