Tips on migrating vanilla React Native to Expo

Thank you. I actually need your opinion on this thread:

Basically, I want to know what will I lose if I migrate from managed to bare workflow in order to setup Stripe payments in IOS? I can leave this feature for the end of the development process, since it’s just one place where the user is paying for the subscription. In the meantime I will focus on getting the rest ready and investigate how’s the sanest way to setup payments in Expo that work on both mobile platforms.
