You should not be able to export your private key from any wallet UI

Unless there was some built in way to proxy an account to another account and making the old one read only, then this would be a UX nightmare.

I get where you’re coming from but there’s so many downsides and edge cases that I can’t agree.

There are ways to do this :)

The second half of this cast that I left off for brevity was something to the effect of "Private key exports are a 'quick fix' for horrible UX that we've collectively decided should be permanent"

I absolutely agree with that last statement.

How do you do migrate? The only way I know of is to permanently move to a smart contract wallet and I’m still on the fence about that one.

There’s so much more than just assets, though. Soulbound NFTs, airdrops your old address is eligible for, any contract that might be using that address to identify you.

I def agree there’s a problem here though, but any good solution I can think of would require an EIP.

You'd just transfer the assets to migrate, the private keys should stay where they were created
