*I dunno, I consider a symmetrical rig that is made **asymmetrical** (and produces an asymmetrical deformation) to be a serious and obvious bug.  Smith Micro's support agrees, although again I doubt they'll fix it. * I wonder if Poser's symmetry is set to the second decimal place?  If so, I can see where one would find it lacking.  

As for the other issues,  I've decided to take matters into my own hands.
