In applications like NMR or MRI you still want to cool down your superconductors as much as possible even if they can handle higher temperatures. As far as I understand this still increases the amount of current they can handle and so increases the maximum field.
The largest commercially available NMR spectrometer has 28 Tesla, and that is a hybrid magnet with both conventional superconductors and high-temperature superconductors. And it's cooled with liquid helium.
