Not that I agree with that, I just think that this is the reasoning.
Yeah, I'd be fine with that. The thing is though, the way it's implemented at most intersections I've seen is that you don't get any pedestrian signal at all if you don't press the button, not just a reduced time. And that's unacceptable.
The point is, if the signal turns on the pedestrian signal, it must provide enough time to cross the entire road. On roads like Fischer Hallman which are 6 lanes + median + bike lanes, this is a fairly long time--for minor sidestreets it would actually have a significant impact on vehicle throughput.
