Personally, I'm happy to lose the data. I found it odd that with both phones and the SIM on the desk in front of me, I couldn't figure out how/if I could vouch for my key changing in any way.

Needing to say I have a new phone just trust me largely defeats the purpose.

If you are on an Android device you can export an encrypted backup and scan a QR code / type in the password to the encrypted archive to transfer messages / group memberships with only a safety number change in most cases.

No dice for iOS unfortunately.

I think that's the opposite of what I want? I want to inform people of the new safety number using the old channel and purge all data like a good user.

In this respect a keybase like model makes more sense to me.

Two small corrections: Signal-Android's backup works with a passphrase only (no QR codes involved) and does not cause safety number changes on restore.

I’m talking about transferring archival data from one phone I own to a different phone I own.

This is different from whether other users are told that my security keys just changed.

Right, I think there's a partial process for what you want and not for informing of key change and I find that backwards AFA security.
