The MacOS native / extension interaction and choice is a mess.
From a UX perspective, the single most important thing the product can do is interact with the browser effectively. Embedded in this "feature" is that the product is stable, and responsive in behavior.
If you go to the chrome web store, 1password extension page and sort by recently updated, you'll see review after review of 1-3 star, carefully explained problems with this product.

Regarding inconsistent messaging, their support is promising they're working on native app integration but there is no timeline for this.
That's why this news is kind of a bummer. The product that I'm subscribed to is competing with this new product for resources.
