At the bottom of the page there is a mention of "Phone-OS - A modern phone OS for ESP32 CYD", so apparently it must be supported.

Most likely. I just checked and it uses embedded-graphics already which means you can plug in Mousefood directly. The touchscreen might be a bit tricky though, it might need some hacking on the event handler side. But it will most likely work if you map the coordinates to the terminal cells abstraction somehow.

Oh bubbletea is really cool. Is this how most interactive CLIs are made?

absolutely, it will work with any other embedded Rust application. The backend only provides a bridge between the embedded-graphics library and the Ratatui widget renderer.

we're bringing back those aesthetics!

Sure, but that's beside the point.

Text based graphics with fancy or custom fonts is just crazy efficient. That is exactly how we got the amazing graphics of The Last Ninja or Turrican on machines with less than 64KiB useable RAM.

Same for more modern embedded devices. If you constrain yourself to text you increase both runtime performance and your developer productivity.
