I think this would increase the amount of noise and by non trivial amounts. As most other forums large and small, work comms tools, etc... are all picking up reactions to messages (vBulletin is soo much better with reactions and MS Teams did a good job picking up reactions too... step up over HipChat).
Also, the point about influencers well... considering the real decision is always in the hands of the Core Team and so far I see tons of people fresh and old contributing it feels like we are thinking of a solution to a problem that is not really here... the attitude of brushing off other’s comments with one liner or attitude self appointed police force statements... those scare people off.
Also, the matter gets more and more complex as the language matures and people may fear the initial curve to contribute and discuss.
