### Description

Currently, Cloudformation only supports import with triggering update/changing resource directly. Task of comparing existing resource with stack template can be tedious.

From [documentation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/resource-import.html)
> Verify that resources and their properties defined in the template match the intended configuration of the resource import to avoid unexpected changes.

Could you add option/feature to import resource without triggering update? this will allow user to detect drift on stack so he does not need to compare it manually.

Start with the AWS CloudFormation resource-import and drift-detection documentation linked in the issue, and clarify whether a no-update import is supported by the service. Define the expected behavior and acceptance criteria for detecting drift without changing the resource or stack; this issue names no repository files, tests, or entry point.
