Yes, I can change the return value and make it work.
However, I’ve used the third party datetime-picker for a lot of functionality during recent years. Its not only for displaying a date and time on a website. Its for schedule import and export of business systems, apis, woocommerce integrations, integrations with booking systems, etc. All these projects will need to be re-tested.
How about disable the new core functionality for datetime-picker if the third party datetime-picker exists?
