If we're talking a 5% reduction in the net heap usage for a react native app at the cost of substantially more error prone code, is that really a win? Hell, make it 10%? These apps still readily fit in mobile hardware, and you wouldn't be using react native on a Pi or other more tightly resources embedded system.
