Working on Farcaster and Warpcast. Longer thoughts at https://dwr.email

Why do you think is good? just the existence of seed phrase sharing functionality, even if encrypted, significantly expands the potential of a hack

firmware update isn't, though. if it was opt-in at that level, I'd agree with you!

Arguably the ability to update firmware without resetting private keys is already a backdoor, allowing them to push firmware that exfiltrate keys. Having an opt-in feature that allow the keys to be escrowed doesn’t make it worse.
