@justinkuntz is anything in your project related to Stripe (or you did not reach that stage yet - this is really a rhetorical question 
)? As you likely know, Stripe just released a beta for Stripe Apps, as different from using Stripe CLI. I believe that your app Next.js Subscription Payments Starter, using the Stripe CLI approach is this correct?
Do you have an opinion about which of these two approaches would you take if starting today. I would also appreciate a comment from @chrisvdm (she is running this project, having limited time on her tasklist), so I am trying to help by establishing best path forward.
My last question is this: in your app, do you use any stripe “components” that have their own UI, like Stripe checkout which simplifies your work, but disables you from invoking only Stripe API, rendering all of your UX yourself?
