This status is for vehicles with lead batteries. Since these can outgas during charging, it is important that the charging station recognizes them and ensures that the charging area is adequately ventilated. Outgassing with these batteries is not unusual, but you have to take it into account. In a garage you would need ventilation for such vehicles, in open parking lots it wouldn't matter.
That's a bit a blast from the past, as type 1 was based on the J1772 connector back from 2001.
