+In-progress API messages
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+These messages are provided for testing and experimentation only.
+They are *not* subject to any compatibility process,
+and therefore can arbitrarily change or disappear at *any* moment.
+Also they may have less than satisfactory testing, making
+them unsuitable for other use than the technology preview.
+If you are intending to use these messages in production projects,
+please collaborate with the feature maintainer on their productization.
