Couldn't we make really thick wires to increase the current limit :) ? After all, there's no need for expensive cooling and the material looks reasonably cheap

  Let's wait to see what the maximum number of A/cm^2 is before determining if that is even necessary. It's possible that they already normalized the figure, and if that's the case then 125 mA/cm^2 would be 'bad news' in the sense that even though the temperature and pressure are much better than other superconductors the critical current is much, much worse. But given the way the paper is formulated I'm not sure if that is a proper reading and it is very well possible that they are talking about a particular thin film sample (which would make it a small fraction of a square centimeter in cross section) and how much current they passed through that sample. In which case the situation would be much better already, especially if it turns out that the sample was extremely thin and/or narrow. Too early to tell without more information.
