IRS 515 says W4 Reset has to create version B (2020). Why is Oracle/PS not updating TAX103.sqr's fun

• IRS 515 says W4 Reset has to create version B (2020)
• Reset W-4 Exempt (TAX103.SQR) Process Not Updating MARRIED_FILE_SINGL field (Doc ID 2517831.1) on 4/1/2019 explains that TAX103 will find the last valid W4 form and set the
  employees values back to what they were before claiming exempt status. The example says the fields updated are SPECIAL_FWT_STATUS, a FWT_MAR_STATUS of Single, a FWT_ADDL_AMT of $150
• What about FWT_allowances which is not available on version B (2020)? If the last valid W4 form version A has a non-zero value for FWT_allowances what happens to it?
