Enabling the same service via Apple Developers meanwhile took me minutes and I never felt lost, confused or frustrated.
Please, Google, just pick a random dev off the street and ask them to do something (that should be) simple on GCloud, then on e.g. Cloudflare. Analyse why they took longer (and cursed more) in GCloud and fix that. The fact that (despite Cloudflare having awful docs as well) my first ever Workers deploy including third-party DNS setup and R2 took less time then getting an API key from GCloud says something
