It was agreed at today's developer meeting that the system preference OpacGroupResults and its associated functionality would be removed in Koha 21.05. It is described in system preferences as, "Use/Don't use PazPar2 to group similar results on the OPAC. This requires that PazPar2 is set up and running." The feature is enabled only .1% of the time: 9 out of 6,405 libraries reporting their usage. If you are among these libraries please plan ahead for the removal of the feature.
