+*Note*: Caution must be used when making use of `Experimental` features,
+particularly within modules that may be used as dependencies (or dependencies
+of dependencies) within a Node.js application. End users may not be aware that
+experimental features are being used, and therefore may experience unexpected
+failures or behavioral changes when changes occur. To help avoid such surprises,
+`Experimental` features may require a command-line flag to explicitly enable
+them, or may cause a process warning to be emitted. By default, such warnings
+are printed to `stderr` and may be handled by attaching a listener to the
+`process.on('warning')` event.
