Would it be possible to reuse `replaceWithAdditionalYields` instead of this helper function? Something along the lines of:
- appending a new yield
- cloning the extract/broadcast outside of the loop
- updating the uses
- let the original extract/broadcast fold away

Not sure if it's worth it. Just thinking out loud...
