I agree this would be cool, and the good news is that systems close to meeting your wishes already exist today.
However, Precursor is more about evidence-based hardware security, and less about features and usability. To better understand the principles behind Precursor's design, please have a look at https://www.crowdsupply.com/sutajio-kosagi/precursor/updates....
The TL;DR is that it's a development platform for applications that strongly require secure and/or trustable hardware.
The platform as usual looks great! I'd ask if you'd consider an addon board, or including an EZR32WG radio chip or similar, as it supports the open source Dash7 radio stack. I'm guessing that being able to tx wirelessly and securely would fit well with the hardware goals.
