this paymaster is version-specific: e.g. the app has to know whether the account is 4337v6, v7 or 7560, and based on that knowledge, select the right paymaster address

That means we need something like a aa_getAccountDetails API, doesn't it?

I don't understand the time-range:
a wallet validation can return a time range, which is compared to "now".
what is the usage scenario of this property?

Wouldn't wallets want to allow dapps to specify the validity range? Seems like artificially limiting a feature we worked hard to add.

The wallet MAY specify a nonceKey, (if it doesn't specify, then the default 0 is used)
nonceSequence is trickier: it requires an eth_getNonce API

We probably need such an API. However, it can be hacked by calling the Nonce Manager directly, but that also gets very version - specific.

i don't think we need this at all - this is exactly what the wallet should do, and not the application. There is no way the wallet can protect the app from a malicious contract.
a wallet defines an account (address).
when the app performs a "sendCall", the wallet should decide how to implement it. if the network supports 7702, it should submit it as a 7702 transaction. if that account already has a 7702 contract deployed (in a previous transaction), then just submit a batch call to use it.

This is a kind of low-level field override. better separate it to a different ERC.
NonceKey and Paymaster are generic, and don't expose the app directly to version-specific API
(paymaster does require protocol-specific paymaster, but it is encapsulated away from the app)
But this one is very specific. Also, it can't be used without a supporting view APIs to query these values
