One thing the original sqm-scripts did (with fq_codel) was explicitly
deprioritize ping with a filter.
I had written in my original "wondershaper must die" rant how stupid
it was to prioritize ping upwards to "impress your friends" - as that
was the case in many, many a wshaper implementation I'd seen.
I only just now noticed that rant does not have the images inline.
"Oh, man, ping's prioritized:"

As for explicit depriorization, well, I took a lot of flack from some
ietfers about lowering it below best effort, and I felt the additional
classification needed was excessive for cake, directly. Some OSes
already do mark it with a background class. I still think it's a good
idea as it makes ping floods against (for example) your entire 10.
network (which happened to me under worm attack once) - vanish.
