Hi,

during the migration between aws.s3.Bucket to aws.s3.BucketV2, i was stuck by dependencies during the removal of the bucket state :

pulumi state delete "urn:pulumi:dev::sandbox::aws:s3/bucket:Bucket::testing1234567-bucket"
warning: This command will edit your stack's state directly. Confirm? Yes

error: urn:pulumi:dev::sandbox::aws:s3/bucket:Bucket::testing1234567-bucket can't be safely deleted because the following resources depend on it:
 * "testing-role-policy" (urn:pulumi:dev::sandbox::aws:iam/policy:Policy::testing-role-policy)
 * "test"          (urn:pulumi:dev::sandbox::aws:iam/rolePolicyAttachment:RolePolicyAttachment::test)

--target-dependents option removes child, so i don't think it will be wanted by users.

I'm not sure what is the best way to fix that without editing the state file.

I don't know how you want to handle this case in the documentation. I think it's going to be pretty widespread.

@fabien-github I think you're running into this issue: BucketV2 to Bucket aliasing is no longer working· pulumi-aws/4471 Unfortunately, it does require some state edits right now to migrate Bucket resources to BucketV2. We'll reevaluate prioritizing a fix there.

@fabien-github do you have an example program showing the old bucket and those dependent resources I can use to walk through this?
