It's a nice thought but we also have to keep in mind that any additions to COE outside of what is already planned, add extra development time to the game. The last thing we want is for a "feature creep" to occur, this most notably occurred with Star Citizen where as it gained more and more backing, its list of features grew and grew until now we're in 2018 waiting for a game that was announced back in 2011 where the game-release had been announced for 2014 (not saying that a feature creep is the only reason but it's probably a contributing factor!) :-)
On the funding side of things, it could also be said that it's not cost effective - especially if the feature requires more than 1 staff member and an extended period of time to create, code, and implement the feature.
