in-progress messages do not give any API stability guarantees,
by design, to allow easy iteration. Provide an easy way
to know which messages are in-progress.
If as a user you see "in-progress" message that you want
to use in production, please contact the feature owner
and discuss the path to removing the "in-progress" status
before that.
