When you have larger machines and higher quality level variance runtime far outweighs any minor improvements made by trying to iterate through every single quality level. This also includes the fact that most people will be running larger circuits that use the majority of the QPU so we cut out large chunks of iterations which can never work due to lack of number of qubits.
