Quenching is less of a concern with HTS coils. They are operated with liquid helium for higher critical current. The HTS is embedded in copper. One argument going on right now is insulated vs uninsulated coils. Insulated are the norm, but uninsulated are virtually impossible to damage from quenching. The copper is a virtual open when the core has zero resistance. When the core quenches then suddenly the windings are all parallel and the coil turns into a single turn copper coil that immediately dumps the current.
