 By removing this data from the transaction structure committed to the transaction merkle tree, several problems are fixed:
 
-# '''Nonintentional malleability becomes impossible'''. Since signature data is no longer part of the transaction hash, changes to how the transaction was signed are no longer relevant to transaction identification. As a solution of transaction malleability, this is superior to the canonical signature approach ([https://github.com/bitcoin/bips/edit/master/bip-0062.mediawiki BIP62]):

 #* It prevents involuntary transaction malleability for any type of scripts, as long as all inputs are signed (with at least one CHECKSIG or CHECKMULTISIG operation)
 #* In the case of an m-of-n CHECKMULTISIG script, a transaction is malleable only with agreement of m private key holders (as opposed to only 1 private key holder with BIP62)
 #* It prevents involuntary transaction malleability due to unknown ECDSA signature malleability

-Currently there is only one nLockTime field in a transaction and all inputs must share the same value. [https://github.com/bitcoin/bips/edit/master/bip-0068.mediawiki BIP68] enables per-input relative-lock-time using the nSequence field, however, with a limited lock-time period and resolution.

-With a soft fork, it is possible to introduce a separate witness structure to allow per-input lock-time and relative-lock-time, and a new script system that could sign and manipulate the new data (like [https://github.com/bitcoin/bips/edit/master/bip-0065.mediawiki BIP65] and [https://github.com/bitcoin/bips/edit/master/bip-0112.mediawiki BIP112]).
