(note: using language that accepts the claims of the paper for simplicity -- I remain skeptical)
For what it's worth, superconductors have a shared budget[1] of (magnetic field, temperature, current). At 25°C, the material is near its critical temperature, so its current-carrying capacity is necessarily diminished. At a lower temperature, the film should be able to carry more current.
That said, 250mA is plenty of current if you're interested in making a superconducting CPU.
