Why garmin can't cast my heartrate automatically?

I'm starting a ride on Edge. The computer has information that the only heart rate sensor I have is in my Garmin smartwatch. Why can't it be connected automatically, since both devices belong to the same ecosystem?

Smartwatch HR measurements during an activity is known to be unreliable, so I guess that Edge has been (sort of deliberately) designed not to connect smartwatch-HR automatically. Most of Edge-based algorithms will not be able to predict accurately any bike-related performance parameters from a smartwatch-HR. Consider getting a quality HR strap if you want to use Edge to calculate your HR-based performance on bike.

I often use my Fenix 7 to Cast HR to my Edge 840. I have to "Start" the casting process, but I've configured a HotKey for that so it only takes one press of a button to start Casting. Once I've done that the Edge picks it up automatically. Having it NOT Casting permanently likely saves some battery power so I don't mind the minimal intervention.

I also have hotkey, but in addition I also do screen blocking afterwards. Casting permanently is not an option, as casting screen will be popping up every time. What I'm asking is auto-casting during activities.

At least in situations when rider has the phone with them, which can act as a bridge to both devices, in case there is a limit to direct bluetooth connection between watches and computer
