Yah Wolf Richter has been referring to it as 'middle age sag of the yield curve.' 
  
 One perspective:  After OP twist and now during QT the long end of the curve may have artificial upwards pressure from these actions of the FED.  If so then the unperturbed curve might look pretty normally inverted instead of 'middle age sag.'
