The U.S. government has charged Samuel Tunick with allegedly typing in a passcode to wipe his phone before officers could search it. “I hope people understand that the charges against me are meant to intimidate people,” he said.

Makes sense; if you can export them, so can an adversary.
Only if they know/think they exist. The idea here would have been to make a nondescript offline backup of the keys and keep them totally seprate from the rest of your data/belongings. Possibly in a geocache type location.
The services (cellebrite) they use to crack normal androids and iphone s would surely let them know that there was an off site backup that likely exists, given that the company doing it knows grapheneOS exists and is used by journalists and their owner's regime is the top murder of journalists in the world
