We're only doing this for the sake of the internal demo and still have a lot of bugs to squash. We could perhaps make a release note about this for 149 though.

Users know that nightly-only features are still under development and to expect problems. We could even call that out in the release note that there are known bugs being worked on.

Added to the Fx148 nightly release notes, please allow 30 minutes for the site to update.
The nightly-only note will be removed after three cycles or when it is enabled by default, whichever comes earlier.
