The biggest game-changer recently is Expo's Continuous Native Generation[0]. You can configure all of your native modules and ios/android files with a simple config file (which has its limits, whereby you'll need to write an Expo Config Plugin[1]). You will no longer commit the ios/android native code to your repository, and instead let it be procedurally built.
This resolved a lot of environment issues developers would often run into, and greatly simplified onboarding new devs. You can build your iOS/Android apps through the CI with ease. And you'll no longer be afraid of upgrading React Native, as Expo will handle all of the breaking changes in the native code for you.
My guess is that Shopify started with bare metal React Native apps (which I would have done the same 5 years ago), and now migrating back to Expo-managed projects is nontrivial. At my work we only manage one app, and it was well worth migrating back.
