Missing getRNIF20Documents service on RN 7.1

We are migrating a couple of PIPs from RN 6.0.1 to 7.1 and found that the services “wm.ip.rnif20.util:getRNIF20Documents” and “wm.ip.rnif11.util:getRNIF11Documents” (used to extract serviceContent and serviceHeader) are no longer available in the WmRNIF20TRP and WmRNIF11TRP packages respectively.
