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.
