Currently, there is no way to deprecate the preview packages that were already promoted to stable.
This issue here compiles the list of packages that need to be deprecated once we have an automated way.
The current list of packages that needs a deprecation notice includes:
packages/react-components/react-breadcrumb-preview
packages/react-components/react-infolabel-preview
packages/react-components/react-message-bar-preview
packages/react-components/react-tags-preview
packages/react-components/react-timepicker-compat-preview
