If you use it in that way, then cut-through is pointless. The whole point of using it is scaling. If you have only "Alice -> Zack" transaction, that is included in some block, then cut-through is really useful. In other cases, if you include all transactions anyway, and create only a proof for some nodes, then it doesn't scale, because you have to always process those transactions in the middle, while there is no need to do so. It is needed only during batching, to prevent double-spending, but if it is deeply confirmed, then who needs something that doesn't scale?
 
Also, going in that direction is a natural consequence of enabling full-RBF: transactions will be replaced, which means mempool-level-batching (ideally non-interactive, done automatically by nodes) will be next, sooner or later.

However, if you want to kill inscriptions, there is another approach, that could be used to force them into second layers: it is called cut-through, and was described in this topic: https://bitcointalk.org/index.php?topic=281848.0 >   > Then, if you have "Alice -> Bob -> ... -> Zack" transaction chain, and for example some inscriptions were created in "Alice -> Bob" transaction, then cut-through could remove those inscriptions, while leaving the payment unaffected, because the proper amount of coins will be received by Zack, as it should be. You are incorrect: cut-through transactions will not meaningfully affect inscriptions. While it is true that with fancy cryptography we can prove the Alice -> ... -> Zack chain, that does not change the fact that Alice -> Bob -> Zack was mined in the blockchain, and those transactions exist. Anyone running a full archival node will still have those transactions, and can provide them (and all their inscription data) to anyone who needs it. This is not unlike how in Bitcoin right now many people run pruned nodes that do not have any archival inscription data. Them running those nodes does not prevent others from running full archival nodes that do make that data available. -- https://petertodd.org 'peter'[:-1]@petertodd.org
