I’m curious if people have run into any issues, particularly freezing when a decent number of these components are visible on the same screen.

From KotlinConf this year we see that CMP can be used as “little or as much” as we want and that it works nicely embedding in SwiftUI.
Colleagues who were there also said it was being pushed that you could use CMP for smaller components to slowly integrate CMP.
I think it should be clearer this approach is maybe not ideal at this time. An image component seemed like a great starting point for a large app, but this limitation stops us doing that.
