To start with, I don’t have an issue with “Creator of the Stars of Night.” Nor with modern treatments of old hymnody–I program/perform them myself. What do you make of the addition of an antiphon to the aforementioned hymn? I had not used this prior to my current parish. I feel ambivalent about it. It’s well-crafted, sure. I didn’t program it this year–no peep from my unofficial music committee.
What’s missing? For me a sense of the tune as something modal, not Western. What do you readers think?

The addition is no improvement. Counterpoint would have been a wiser approach.
