How would such a node treat a transaction that spends multiple dust UTXOs and creates a single non-dust UTXO out of them (after fees)?
Is it valid (to such a node) or not?
I presume from #1 it never stores dust UTXOs, so the node cannot know if the UTXO being spent by such a tx is spending dust, or trying to spend an already-spent TXO, or even inventing a TXO out of `/dev/random`.
