+In terms of new functionality, [BIP 118 `SIGHASH_ANYPREVOUT`][apo-bip] enables rebindable signatures and their applications, including covenants inexpressible under the current proposal.
+However, it does not enable delegation.

+In terms of semantics, BIP 118 extends Bitcoin semantics in subtle ways, making future updates building on it tricky to reason about.
+On the other hand, the new operations proposed here are intuitive and, since they are opcodes, semantic changes are confined inside of Script.
+As such, they add useful functionality while keeping under control the extra cognitive load needed to design future updates.

 An alternative to [BIP 446 `OP_TEMPLATEHASH`][templatehash-bip] is [BIP 119 `OP_CHECKTEMPLATEVERIFY`][ctv-bip]. This
 proposal favours the minimal approach of [BIP 446 `OP_TEMPLATEHASH`][templatehash-bip] that does not modify legacy
 scripting contexts and reuses the existing Taproot signature hashes. See [the rationale section of BIP
