Yes, that would be useful.

And it does (yes, I looked at the patch;->).

If you removed it entirely (and had it as a separate classifier) IMO
that would be a better approach. Then what you have is a pure FQ qdisc.
In which case, you leave alone SFQ and have a new qdisc.
The "removed" hashing dynamic classifier would of course be better off
it allowed the user to select a hash algorithm such as the other ones
specified in ESFQ.
