Is there any hard limitation that prevents synthesizing in bulk? If not, I would not worry about this at the moment and if it proves to be a material with desirable properties just leave it up to the engineers who will hopefully find a suitable production process.
There’s not really such a thing as superconductivity for a fine powder, so people are having trouble determining if this material even superconducts.
edit to clarify: Bulk here refers to having a single chunk of the material, and does not refer to the total quantity. Some physical properties only exist or only surface in chunks of material, not in the powder form.
Conversely, the tape-type high temperature superconductors are generally made with a colloidal deposition process - which is based on a powder as a starter material.
Assuming this is real, that would be the obvious process by which to try and build useful conductors and magnets - it also suggests a refinement process (passing it over a magnet would quantum lock superconducting grains and let the rest slide off).
