While React Native is constantly being improved, to use it in its current form, one has to be very aware of its under-developed parts, and more importantly, make them aware of by designers and PMs.

Surely for any "fancy" feature one may think of doing with RN, there are always some libraries, plugins, tutorials, solutions that exist in the vast ecosystem trying to help. But more often than not they eventually lead into a maintenance/integration nightmare, simply because how fast the whole mobile industry moves and leaves things behind.

Therefore, I suppose that a wise approach is what I would call "React Native-first design": let the whole team (PMs, designers, devs) know that anything that is not officially supported by React Native and without caveats is off the limit -- just try to avoid the design until it is fully supported.
