It is cool feature but to what end? Buying a domain is not something you have to do daily to require any kind of automation.
I am also not sure who Stripe Atlas for. I am genuinely confused. It is definitely not something a developer will use.
I understand that you can bootstrap a number of systems but that is like half-hour of work and arguably it is probably a good idea to do it manually to make sure you have strong foundations.
I've have personally never seen a good example where a cross vendor account provisioning actually working. For example, Fly.io used to provision Sentry accounts automatically which you could not access in any other way but through Fly.io. I mean the Sentry account was effectively locked to a project that you cannot transfer - hijacking the actual global alias as well. Vercel did something similar with PostgreSQL via Neon and Redis via Upstash resulting in painful migration processes.
I can imagine ending in some kind of deadlock between services due to security hence why the 30 minutes initial setup is kind of time well spent to avoid future issues.
Maybe it's me.
