This is big news, especially if it can be scaled to production. There are numerous potential uses for superconducting magnets that are simply impractical due to the availability and cost of liquid helium and the difficulties of designing equipment to operate at about 4 K.

As the article points out, once they figure out the atomic arrangement it should provide more clues.

IIRC, 'Nature' withdrew that team's previous paper when no-one was able to reproduce the effects using published recipe.

Not saying 'was wrong', as eg 'twisted graphene' took a long time and much serendipity to figure.
Due care, please ??

Yes, they did but this looks a lot better in terms of the details.

We don't need superconductivity at ambient temperatures for it to be a game changer, -40C to -60C isn't that difficult. Those sort of temperatures are easier to reach than 10 kBar pressures, and would still create a revolution. That's not to put a downer on the research, which is still impressive.
