Of course I can't make any strong claims before actually doing the work, but it seems to me that if one added the missing JCM for the larger x-rotations of the thigh - which I omitted in part because I foolishly believed that the human hip could not bend that far, but also because I was forced to use the workflow from hell and got worn down by it eventually - 1.2.0 would win on all counts.

As always of course, your mileage may vary.
