What I had in mind was proceeding with a proposal like this one where we
change ACLs to have multiple stages.  This patch proposed two, but I think
we later talked about extending it to have more (8 perhaps?).

Then if SFC was an ACL action, you could put it in any stage of ACLs you
want, with other things before or after as desired.
