 ## 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>)
-        * [Tracking Issue](<Tracking Issue URL>)
-        * [Testing steps](<Testing Steps URL>)
--->
-<!-- or if there are no new or updated RFCs this week, use: -->
-<!-- * *No New or Updated RFCs were created this week.* -->
-<!-- Remember to remove the `call-for-testing` label from the RFC so that the maintainer can signal for testers again, if desired. -->
