This comment refers to a feature that hasn't yet been sent upstream.
...but it's a good reminder and I can send it upstream now. You can
see it at:
* https://chromium-review.googlesource.com/62630
* https://chromium-review.googlesource.com/175653
Since this is only a comment I guess it's OK to refer to a feature
that hasn't yet landed (?).

This is also referring to something that hasn't been sent upstream yet. See:

polling mode change mentioned above.
