I was under the impression that Antonia-WW was merely a "Support" figure to be using in conjunction with a renaming python script to get clothing converted to Antonia 1.0 following these steps:

1: Convert clothing to Antonia-WW
2: Run Renaming Script to rename all the body parts in new converted clothing to Antonia 1.0 conventions using the renaming Script.
3: Apply clothing to Antonia 1.0 and pose to your hearts content.

I never saw her as an update.

This would preclude the need for an Antonia WD. Antonia-WW being merely a tool for converting clothing to Antonia 1.0. It certainly seems a simpler more elegant solution considering walk designer and Poser want to do things to the hip that they want to do.
