 ## Calls for Testing
-
 An important step for RFC implementation is for people to experiment with the
-implementation and give feedback, especially before stabilization.  The following
-RFCs would benefit from user testing before moving forward:
-
-<!-- Calls for Testing go here, use this format:
-    * [<RFC Topic>](<RFC URL>)
