Thank you for your interest in UI for NativeScript.
Indeed, enabling both components for usage in an Angular 2 project is on our near-term roadmap as we also feel those are important for real-life business applications. We're currently concentrating on getting ready for NativeScript 3.0
due by the end of the month and plan to start working on this soon after that.
I hope this timeline fits your needs.
