I can easily see specific hardware being included in future devices to support improved contact tracing – especially if COVID-19 becomes endemic. That could be new low-power proximity detection hardware, or extensions to BTLE protocol and hardware.

Maybe opt-in like the "Emergency Alerts" notification functionality?
