The Cost and Usage Reports legacy page will be deprecated on June 1, 2024
Data exports is the new experience to export your cost and usage reports and more. As a result, the Cost and Usage Reports legacy page is pending deprecation. You’ll continue to have access to Cost and Usage Reports, the customer carbon footprint tool, and the AWS usage report from data exports.

Based on the above snippet from AWS we likely need to update the wizard to handle the differences in how these reports are created. Whether Cost supports the new report type or not, the wizard will still need a subtle change for legacy reports.
