OK, so there's another doll inside the Matryoshka, a 'v6' option.  Apparently 
what John implemented is version 6 and must remain.  The hggroup is an 
additional factor.  The stem series was may have been introduced because of the 
fact the more object-like handle for each line was too slow to render.

It seems to me this is mostly a matter of programming and it is close to 
compatible as it is.
