We would like to see airplane mode enabled on first launch
Also we're pretty sure that a recent update caused airplane mode to be disabled after a reboot (pixel 8 pro)
A developer setting to force airplane mode at all times wpuld be great
Researchers at Trinity College Dublin, lead by Professor Doug Leith did a report to determine if Airplane Mode in #GrapheneOS and other devices actually disabled cellular. It doesnt have any cellular transmissions.

There is a radio activity spike at the 2.4GHz band, this suggests Wi-Fi activity and is different from cellular network activity.
