Core's conservative view on hard forks is what has made Bitcoin survive for 7+ years. Look at the ETH/ETC disaster. We must not hard fork unless we have like 99% of support.
How could we ever know that we
have 99% support behind a fork? There's no way to measure it. No amount of node voting, coin voting or miner voting can establish that. More to the point, if we are talking about processing power, hash rate of ETH:ETC was 99:1 at one point. Still, the network split. People really underestimate the risks. There is literally no way to ever know how a hard fork will resolve. It's impossible to know.
