I'm actually not that interested in an academic competition about what 
solution gives the ultimate "best" outcome in simulation or in a lab.

I am interested in good enough solutions that are actually deployable and 
will get deployed, and doesn't have any pathological behaviour when it 
comes to legacy traffic.

Right now the Internet is full of deep FIFOs and they're not going away, 
and they're not getting FQ_CODEL or CAKE.

CAKE/FQ_CODEL is nice, but it's not being deployed at the typical 
congestion points we have in real life. These devices would have a much 
easier time getting PIE or even RED, if it was just implemented.
