> Could anyone propose a better use case of CODESEPARATOR?
Long ago, aj sent an email on Lightning-dev about use of CODESEPARATOR to impose Scriptless Script even without Schnorr. It involved 3 signatures with different CODESEPARATOR places, and forced R reuse so that the signatures to claim the funds revealed the privkey.
The script shown had all CODESEPARATOR in a single branch.
I cannot claim to understand the script, and am having difficulty digging through the mailinglist
