Are you sure it works for vast majority of users? At least in my developers circle who use macOS for web* development - all of them have issues with docker high cpu usage due IO. Some use docker-sync to go around the issue.

As for bug reports - zero feedback from anyone on that thread from maintainers. If you are one of the maintainers - it might be good to write this comment on that thread instead of HN

* - I understand that web developers might be a small percentage of users and my case doesn't represent everybody
