If Segwit needs 95% signalling to be "safe", why wasn't it implemented as a Hardfork with 95% signalling?

As a sideline watcher for 2+ years, this is what I shake my head at everyday.A 95% signalling Hardfork Segwit + 2Mb blocks would have easily gotten 95% of the community behind it. Such a simple compromise. Tragic that it didn't happen.But, my question is still serious. With 95% needed, why not implement a cleaner hardfork? via /r/Bitcoin http://bit.ly/2kyGWZm
