Slightly off topic, but I feel like pointing out that this is not limited to their recent/model offerings. I recently had to once again enable both Sign in with Apple and Google, yet despite having done so at least three times throughout my life (Auth0 back in the day, BetterAuth last year, now WorkOS AuthKit) and having access to modern models, it was an exercise in frustration, outdated official documentation and permissions errors that were beyond inconsistent, at least on the GCP side.

Enabling the same service via Apple Developers meanwhile took me minutes and I never felt lost, confused or frustrated.

Azure did this.

Those devs were clearly a lot smarter than me, then.

They do return their services if you search for the name of some AWS services, which is helpful.
