I'm a layperson skimming in a hurry, but it looks like this is actually "our findings with material A may be transferable to material B", which is very close to a room-temp superconductor but doesn't seem to be the same thing as "here, I have a chunk of it on my desk". to quote the conclusion: "In conclusion, we have demonstrated that the pressure-induced/enhanced superconducting phases with high Tc and the pressure-induced semiconducting phases in FeSe and Cu-doped FeSe can be stabilized at ambient without pressure by pressure-quenching at chosen pressures and temperatures. Theses pressure-quenched phases have been shown to be stable at up to 300 K and for up to at least 7 days. The observations suggest that the recently reported room-temperature superconductivity in hydrides close to 300 GPa may be retained without pressure, making possible the ubiquitous applications of superconductivity envisioned"
