+TEMPLATE_MESSAGE = <<~MSG
+This merge request requires coordination with gitaly deployments.
+Before merging this merge request we should verify that gitaly
+running in production already implements the new gRPC interface
+included here.
+
+Failing to do so will introduce a [non backward compatible
+change](https://docs.gitlab.com/ee/development/multi_version_compatibility.html)
+during canary depoyment that can cause an incident.
+
+1. Identify the gitaly MR introducing the new interface
+1. Verify that the environment widget contains a `gprd` deployment
