You know what would be good for security:
Having physical disconnect switches (Bluetooth/Wifi, Modem, Power, Microphone/Speaker), and integrated lens cover like Lenovo laptops (at least for the front camera whereas a case can cover the rear cameras).
On a side-note:
Triple active SIM would be amazing, but one can dream. I would love to have a phone that has an active AT&T, T-Mobile, and Verizon SIM at the same time.
Also a disconnect switch for the telco signal. Yet in my experience, even when turned off, a phone may send out a signal periodically anyway for tracking / triangulation purposes.
However to avoid that, removal of the battery is required. A disconnect switch for power would do the same?
I think moving to micro-PCs is the answer, and then having an add-on to get a telco-signal. Why trust Motorola? Start at grass roots where possible. Everything needs to be open-source and based on open standards. No trojans, telemetry or remote overrides.
Maybe the product is an adapter case for a Pi that adds a screen, battery, antenna and whatever else is required to make it a smartphone alternative?
Also, looking forward to Mecha Comet.

You can fit several esims on one of these adapters AIUI.
Removable battery
That's just security theater. If you can't trust the very CPU/OS that it only uses the camera/microphone when the notification is on, then what are you even doing with that device?
Google Fi will auto-switch between AT&T and T-Mobile but not Verizon, AFAIK.
