I am the worlds biggest fan of Opus. I use it like crazy. And I will always support you by using the latest version.
But a huge amount of the capability of Opus is "over my head." (And my setup is pretty complex.)
That's why bringing these types of things into the interface allows users who aren't experts in all of the under-the-hood functionality to benefit from them. If you can already make a script to talk to ChatGPT, then please do and let us benefit! 
Plus, if you're looking for a "Marketing Headline" in 2024 -- saying that you can do AI renames is bound to draw sales.
