In the "My documents" section, you can see the creation date on the list, but if you use the search feature, it only shows you the "modified date" and doesn't give you the option to see the created date. i wouldn't mind a whole separate option for it or still being able to change the modified date column to the created date column. Sometimes we are looking for patterns with templates failing or getting stuck in draft from our API and it's more helpful to see the created date then it is the modified date.
