<p>It makes signatures faster to verify, makes singlesigs and multisigs indistinguishable, hides unused parts of the ScriptPubKey, makes softforks easier (by replacing OP_NOPs with OP_SUCCESS:es), and potentially enables us to implement <a href="https://bitcoin.stackexchange.com/questions/106241/what-is-cross-input-signature-aggregation-and-how-would-it-work" target="_blank">CISA</a> in a future soft fork, which would make consolidation, batch, coinjoin and payjoin transactions significantly smaller and thus cheaper.</p>
