What it really is is basically a consensus between participants. Once the consensus about a change gains critical mass, that change just happens, by someone coding it into the software and people updating to it. The change (fork) becomes mainstream and the old version becomes fringe. And vice versa, if consensus never achieved. There will be people who stay on old version anyway. It’s up to who believes in what, based on available software based on ideas that are worth new code.
