Attempting to prepare site for Drupal 10 upgrade. Need guidance concerning the expected impact/outcome on user accounts when uninstalling the RDF module, which was enabled only in the (Acquia) AMA environment during migrations from Drupal 7 to Drupal 9 prior to AMA becoming open source. This module was not enabled in the D7 production environment.
When attempting to uninstall the RDF module in D9, I received a warning that “The following modules will be completely uninstalled from your site, and all data from these modules will be lost! RDF”. Then under “Configuration deletions”, it states the RDF mapping for user.user will be deleted. See attached screenshot.
So it's just saying it will delete all info and configurations tied to RDF.
