Describe the bug

Release v2.163.0 has introduced a breaking change for customers who do not bootstrap their AWS CDK accounts and publish assets / artifacts to S3 buckets that lives a different AWS account.

Regression Issue

• Select this option if this issue appears to be a regression.

Last Known Working CDK Version

v2.162.1

Expected Behavior

For accounts that are not bootstrapped, CDK should allow to publish assets / artifacts to S3 bucket in cross account.

Current Behavior

We do not bootstrap our target deployment accounts. We also package & publish the deploying assets / artifacts into a S3 bucket that is managed in a central account to be used during CDK deploy. The change introduced in determineAllowCrossAccountAssetPublishing as part of “disallow cross account asset publishing in some scenarios (#31623) (edd031d)” is breaking our pipelines from publishing assets cross account and eventually failing to deploy.

Reproduction Steps

• Do not bootstrap an account
• As part of pipeline, try to publish an asset / artifact (to be eventually used during deploy) into a S3 bucket that lives in a different account

Possible Solution

This function determineAllowCrossAccountAssetPublishing should be enhanced to allow cross account publishing for customers who do not bootstrap their AWS CDK accounts.
