Not really, that's just basic access control. If you've used Colab or Cloud Shell (or even just Google Cloud in general, given the need to explicitly allow the usage of each service), it's not surprising at all.
Why does AI studio need access to my drive in order to run someone else's prompt? It's not a prompt for authentication with my Google account. I'm already signed in. It's prompting for what appears to be full read/write access to my drive account. No thanks.
