Bitcoin Core v0.21.1

`bitcoin-cli walletprocesspsbt` does not trigger a `wallet locked please enter passphrase` warning when using a wallet which holds private keys. To be clear I am experiencing this behavior when using the `default` wallet created by core.

The expected behavior would be to remind the user they are dealing with an encrypted wallet, since `walletprocesspsbt` attempts to access private keys to sign the psbt. It would be useful if a warning were present in the rpc response to remind the user they are dealing with an encrypted wallet.

                "The inputs added will not be signed, use signrawtransactionwithkey\n"
                " or signrawtransactionwithwallet for that.\n"
