10  - `gettxspendingprevout` has 2 new optional arguments: `mempool_only` and `return_spending_tx`.
11    If `mempool_only` is true it will limit scans to the mempool even if `txospenderindex` is available.
12    If `return_spending_tx` is true, the full spending tx will be returned.
13    In addition if `txospenderindex` is available and a confirmed spending transaction is found,
14    its block hash will be returned. (#24539)
