You should write your operator. You are correct: it is quite straightforward and you'll have solid understanding of what is happening and how it works.

That is how this project started. We wrote custom operators for the various platform components; that worked outstandingly well. Shockingly well to be honest.

This system evolved from that approach because we needed a way to rapidly customize our application models. If you don't need to support varied use cases _and_ have standardization writing your own is the way to go.
