+// values, but they may be subject to change between API versions. This function
+// is intentionally not registered in the scheme as a "normal" `SetDefaults_Foo`
+// function to allow consumers of this type to set whatever defaults for their
+// embedded configs. Forcing consumers to use these defaults would be problematic
+// as defaulting in the scheme is done as part of the conversion, and there would
+// be no easy way to opt-out. Instead, if you want to use this defaulting method
+// run it in your wrapper struct of this type in its `SetDefaults_` method.
