[Bloat] How is bufferbloat prevented/fixed for UDP?

Curiously, there is little information to be found regarding bufferbloat
and UDP.

I did find hints briefly alluding to some problems:

1)With UDP, you cannot uniquely identify a flow? This prevents an
AQM-algorithm to drop packets for an (several) offending UDP flow(s).

2) Unlike TCP, UDP does not back down when encountering packet loss

So how does UDP fit in concerning efforts to combat bufferbloat? Having one
queue to mange all UDP 'flows' does not seem like a good approach.

Thanks for shining a light on this:-)
