Are those outputs stuck in limbo until the transaction is included in a block?
What if, hypothetically, the mempool never cleared? How can the user ever spend those outputs again?
Is there a way to find out how many of the transactions in the mempool aren't using RBF?
Is the only solution to hire someone with a ton of hash to include it for you through some offchain channel?
This seems like an absolute nightmare scenario that many people will be stepping into accidentally these days...
