[5] An update on Object.observe ( 版) <https://esdiscuss.org/topic/an-update-on-object-observe>
After much discussion with the parties involved, I plan to withdraw the Object.observe proposal from TC39 (where it currently sits at stage 2 in the ES spec process), and hope to remove support from V8 by the end of the year (the feature is used on 0.0169% of Chrome pageviews, according to chromestatus.com).
