Record but not Alert in People Only Mode for Hardwired devices

I am looking to reduce the amount of notifications I get. I have a Floodlight Cam. I was looking at the People Only mode and I see that for BATTERY powered devices it works the way I want it to, which is that it still records for any event but only sends an alert for events a person is detected in. However, for Hardwired devices like my Floodlight Cam, it will not even record unless it detects the human shape. I don't understand why there would be this difference, why not just make this a setting change, and if anything makes sense it would be the reverse - a hardwired camera should be able to record as much as you want, it would be the battery powered cameras that you would want to reduce recording time on in order to save battery.
