+    Enable the Go disk and network core checks by default for Windows and Linux.
+    These are direct ports of the existing Python disk and network checks and allow
+    the Python runtime to be lazy loaded when other integrations are enabled. It
+    can be disabled with setting ``use_diskv2_check`` and ``use_networkv2_check``
+    respectively along with the loader in your configuration to use the Python
+    version.
