US carriers (including mine) usually just leave the "minimums" at the baro minimum for whatever approach you have briefed as backup to your visual, or baro mins at 200 AFE otherwise. RA mins are in my experience at least generally only used for cat 2 and 3 approaches. These approaches have been flight checked and certified at RA minimums, so you are guaranteed to not have false minimums call outs due to terrain contouring, as previously pointed out.
One logical reason for keeping a "minimum" set as SOP on a visual is to prompt the flying pilot to make a "landing" callout sometime just before the flare. This is a last minute "I'm still alive" check to confirm to the pilot monitoring that the PF is in fact not incapacitated at the most critical point in the arrival.
