this is exactly the problem in production environments; workloads can be 'bursty' which can see not-insignificant performance reduction when using powersave. Many enterprise users even go so far as to disable C-states (and ASPM, and APST, etc...).

for laptop users, yeah. I question if 'most scenarios' is accurate.
