Naming a horse Mejiro nowadays without it having any actual corrections to the ranch is likely considered taboo among Japanese horse racing fans, if a random horse got the Mejiro prefix slapped to their name there would be an outrage and the JRA would likely have to get involved.
The only one allowed this right nowadays is Mejiro Piola since she's a direct descendant of Mejiro Dober, one of the last of the throughbreds the ranch produced.
