Is there a documentation error on certificatepkcs12?

https://developer.apple.com/documentation/devicemanagement/certificatepkcs12
The document states that this is not for user channel for shared iPad, only for macOS. Doesn't an identity cert have to be sent with a vpn, exchange, email payload? Does that imply we can only use these payloads with identity certs in device channel?
