Smart wallets (passkey based) are so important. They are the most flexible form of an account, and as passkeys grow the network effects will increase. 

For example, adding a passkey to a shared group in Apple Passwords is the new way to create a family wallet.

You can also upgrade a smart wallet to be a multisig, pay fees in tokens, add social logins or hardware keys, skip browser extensions, etc

I'm sure there's more use cases, but I do feel it is like the iPhone moment of experience.

Given all this, I don't think development is going quick enough.
