### Environment details (OS name and version, etc.)

Start by reading the referenced issue #954 and reviewing how AWS CDK currently handles deployment patterns. The issue provides no files, tests, or proposed implementation; done would require an agreed, supported zero-downtime deployment pattern for the requested S3 use case.
