So does everyone know that if we don't use text_prefix and say use a standard string like JMODEL_ACL_ERROR_DELETE_NOT_PERMITTED, that extension developers can still override this by just adding
 MODEL_ACL_ERROR_DELETE_NOT_PERMITTED = "Whatever their custom message is"

In their INI file which will only affect their extension messages AND give everyone a standard set of messages to translate, which would still work even if the developer didn't translate his/her extension into every language used in Joomla?

What was the point of the prefix again?
