I'm not a Hanabi player, and in general do not understand "hardcore cooperative" mentality, but based on the discussion here it seems folks were using Elo as a tracker/measurement of experience. It allowed to choose more complex conventions with more experienced players (presumably it is like Bridge conventions, but I can be totally wrong here). Also some folks used Elo as a self reward.
Regardless, it was useful for them for some reason. So, I wonder who was the customer of the change? Who requested the change and is happier now, after Elo is hidden?
