 There is nothing stopping you from specifying two `artifact` elements with the exact same values.  So you can ban multiple version ranges of the same artifact by using multiple `artifact` elements.
 
 If you *include* all versions by omitting the `version` element, you can still *exclude* (unban) certain versions, like `[1.2.17,)`.
-
-It is recommended that you look into [Maven Tiles](https://github.com/repaint-io/maven-tiles) so you can use a tile to define your banned artifacts and side load them into all your projects.
