If you let me know where the draft implied that you were
advocating per-flow policing, I would be happy to correct it.
(I looked, but I didn't see it.)

The draft is not intended to be about any specific proposed mechanism.
It is simply in support of "simple best-effort traffic", and in support 
of
flow-based fairness for simple best-effort traffic.
