I hate to be the bearer of bad news, but this feature request has been declined.
We acknowledge the customer demand for Private Channels and have been hard at work on it. Private Channels is currently in preview with a select group of customers. We expect to release the feature to the public later this Fall, and will update here when we are starting to roll out to all customers. We appreciate all the feedback you have provided to us on this forum and thank you for your patience.
This would be hugely useful to me - to include external stakeholders on a project by project basis without having to add them to the team
This request has been declined by the feature team.

Thank you all for the feedback.
Reading through my comment again, the more common requirement is to invite internal stakeholders into a channel - that is to say people who are not in the IT team but who are involved in the development of a specific new capability.
I have an department (set up as a team) running various projects (set up as channels).
What I would dearly love to be able to do is invite individuals outside the team to join a project (channel)
For example, one of our projects is to roll out Office 365. MS Teams is a very good tool for managing the various elements of this project - notes, chat, planner, documents etc.
The obvious thing to do is to set this up as a channel. However, because we have engaged an external consultant to help us with the transition, we have to set it up as a team instead.
This requirement is very common as most of our projects involve a few individuals outside our core team: stakeholders and/or people with special skills brought in on a project basis.
For this reason I think it would be very useful to invite people outside the core team to join a channel.
