Opportunistic suspend is just a deep idle state, nothing else. If the overall QoS requirements allow to enter that deep idle state then the kernel goes there. Same decision as for all other idle states. You don't need any user space blocker for this decision, just sensible QoS information.
agree completely with you. Adding virtual differences between power states is a bad idea and causes unnecessary complication to the system. If we have a generic way of describing desired latencies (irq, wakeup, throughput, whatever), then the kernel should decide what's the best power state for the current situation.
