Why no broadlink S1C support in docs, although python-broadlink has such support

Library python-broadlink has such support, https://github.com/mjg59/python-broadlink/blob/dfd478922b34b7810743b3bf145bed3026159838/broadlink/init.py You can see constant

    0x31: 'Door Sensor',  # 49 as hex
    0x91: 'Key Fob',  # 145 as hex, as serial on fob corpse
    0x21: 'Motion Sensor'  # 33 as hex

but in HA docs there is no such sensor https://www.home-assistant.io/integrations/broadlink/#sensor We have only RM2 and A1 E-air
