Funny, since AWS has much more granular control over IAM roles and users than GCP does, so that the infrastructure/security group should be able to provision devs with the ability to roll their own IAM in a scoped way to prevent issues.

This requires money and time that often only large corporations have the luxury of.

In my experience trying to configure AAD policies, AWS IAM and (to a very limited extent GCP IAM), it does not generally require a large investment in time. It does require a development account in which the developer has full access to IAM/AAD.

At my employer, we have a gatekeeper team who is terribly overworked and hardpressed to push back too much when business outcomes are at stake. One of the more successful things theyve done is create a terraform repo anyone can contribute to. They will review PRs and manually apply changes for production accounts. Whats great is that these folks can take my PRs that are 80% right and they are able to help me achieve least privilege better than I could on my own. However, other devs really dont care about least privilege and they tend to go for large open policies.

AWS's IAM policy is far and away the most sophiscated and granular, and even has a nice UI now. Trying to achieve this in Azure is next to impossible because you must have extremely high permissions to even be able to make new roles/policies that are super granular.

Also, permissions boundaries are specifically made for the use case of "IAM teams delegating some control to devs".

IAM team creates a "developer admin" role/user that can only create users/roles that have a permissions boundary on it. That way, no matter what policy the dev admin grants, the dev user can only do what the permission boundary allows.

(A) Not necessarily, and (B) if so, okay so what? The whole point of the parent comment was about keeping devs in check, and I submitted an anecdote that AWS in fact has better tooling to keep people from doing things they aren't supposed to. Not related to billing oversight, but permissions.
