// Disable disables lazy unmarshaling of opaque messages.
//
// Messages which are still on the OPEN or HYBRID API level (see
-// http://go/go-opaque-proto) are never lazily unmarshalled.
+// https://protobuf.dev/reference/go/opaque-migration/) are never lazily
+// unmarshalled.

// Fields must be annotated with [lazy = true] in their .proto file to become
// eligible for lazy unmarshaling.
