Can vouch, I put in a request for 20 projects extra which was approved in hours.

Many products using the Cloud APIs auto-create projects. I know of AI Studio and Google Script (including scripts embedded in Docs, Sheets, etc)

So many organizations have the IAM "Project creator" role assigned to everyone at the org level. I think it's even a default.

As long as you are over a certain spend. I started something for my own project and went to apply the recommended architecture, which does not work without a quota increase. As it was from a fresh account, the email was we won't look at this until you spend or pre spend so much money. Frankly, for a trail period when evaluating at prior enterprises, that would have made me just say no to their cloud. One expects that the recommended architecture can be deployed in the trial run without hoops.
