As others, from the videos, I really like the tight Xcode integration. Reading the FAQ I do have few concerns,

1. Open-source, it mentions GPL forms, is there a reason MIT not mentioned? is that not considered open-source (especially with many iOS/Swift using MIT to be compliant with store distribution).

2. Packages, how does it handled packages? or the cases when you need to have branching for iOS/Android? the FAQ does not address this.

3. How Apple service APIs being handled on Android? I didn't look at the example weather app, but as an example, Apple got WeatherKit. or in my case case I use the built-in geolocation APIs.

My concrete example, I have a small app I've made. It uses geolocation from Apple (to detect country city, etc), It uses AdMob and Apple's built-in In-App / Subscription services.

I think this is a fair example of simple commercial product, and it'll be nice if you have some example for ads and in-app/subscription which might be important for closed/paid monetized projects...
