blockchain – Sign an empty entry?

Is it possible to include an empty entry in a transaction?

For example, an empty entry could be used to guarantee a exit was included in a transaction, using SIGHASH_SINGLE | ANYONECANPAY in combination with SIGHASH_NONE.

Of course, you would still need to include the miners' fees in another input.

Correct me if I'm wrong, but although to spend utxos to 0 result is legal, it is quite difficult to generate utxos 0 result, Bitcoin Core does not generate these transactions below the dust limit.

Likewise, OP_RETURN provides utxos at output 0, but they can not be spent as part of a sighash_singlebecause they are priceless.
