Welcome here!
Very good observation... and actually, this is intended. For historical reasons, rings and cones are not normalized. Rounding is done this way for ring and cones (ok, seems weird at first sight!!!) so their vertices match exactly those of scaled normalized primitives (edges, cylis, discs and so on...)
Yes, this is intentional for the reasons Philo explains.
