We have successfully used this feature in Fuchsia and found it useful, but I agree that the issues raised need to be addressed. Unfortunately @paulkirth is no longer working on this project. I hope that someone from our team can take a look but it might take a few weeks. If you prefer, we could revert this change and then reland an improved version in the future?

Sorry for the late reply. Since @paulkirth is no longer working on this project. I can take over it and start working on it full time beginning next week. It would take me some time to get familiar with the code and work on the fix though. If you still prefer reverting this change, we can work on an improved version and reland it in the future.
