Should there be a system level setting to turn off those power optimizations, if they're known to not be compatible with "all" (taken as a metaphorical term) access point / router devices?

There is. You could try turning off settings > wifi > advanced > wi-fi optimization

 to see if it makes a difference.

Thank you. I never noticed that before. Must be new in 4.2? 

 

The HIGH_PERF API also does the same and should be used with care due to power impact.

Can you give an estimate how much more power this will consume?

I do not have the numbers with me now, but this really depends on the driver and the environment (amount of traffic on air)

I believe in our tests at google, the idle power went up 5 times.
