Better would be to work towards a general cpuidle.max_state= param which deprecates processor.max_cstate= (acpi_idle driver) and intel_idle.max_cstate= and enables this functionality for all other cpuidle drivers out there as well.
Something to turn off intel_idle driver and favor the acpi_idle driver for debugging would still be needed then.
