Delayed-based RED still would associate latency with drop probability:
drop probability will only go up when queueing latency goes up. A higher
drop probability can only be achieved via higher queueing latency.
If following Bob's statements last IETF, this could even be a desirable
feature:

Hi,
while looking at the PIE presentation
http://www.ietf.org/proceedings/86/slides/slides-86-iccrg-5.pdf,
slide 6 shows that RED is far away from the PIE
queuing delay. However, I'm not sure that this comparison is
really fair if looking at the choice of the parameters.
The buffer limit is set
In the real world, the hardware buffer size is rarely matched to the real
BDP. There are several reasons for this, but a couple of fundamental ones
are:
- BDP varies with RTT, which is in general different for flows
simultaneously using the same link/queue to reach different remote hosts,
and
