Obviously we must choose decentralized and slow adoption. What use does Bitcoin have if the network becomes centralized? This is why we must keep supporting Core. They are conservative, the progress is rather slow but it is solid and well thought, no improvisation and keeping the network decentralized is the priority.
lol delaying freedom of choice with words like year development and year grace period.. is not cautious security.. but delay/avoidance tactic to then push through their own rules that doesnt even need 6000 nodes to upgrade/consent to, and activated in under a year
analogy:
"we dont want to get into a car to go to the shop, so we think it will take 2 days to walk it and avoid car crashes.. but we want to invent a motorbike with an invisible side-car and will get to the shops in one day"
core is centralized. (even you admit they are a powerful team)
core is centralized. (a dozen paid coders and 90+ spell checkers doesnt make them decentralized)
much like UK parliament where 650 MP's live in different towns but make decisions together, is not decentralized
much like US government where senators live in different towns but make decisions together, is not decentralized
but core has become the prime minister/president that can sway the debate in their direction, veto and disregard.
in short..
if your are defending the power a group has about the rules.. its not decentralized.
every group should be on the same level in regards to the consensus
as for the social preference of which implementation. then that is not about the rules, but about the function, speed, errors, GUI interface and openness of each team. (total different argument to the consensus mechanism)
You are overcompensating things. People choose to run the Core software, this means they like the developer team and how they get things done.
Everyone is free to try to improve the software, but of course it needs to go under revision by experts, as you have been told, if we let every idiot out there push their code into the project it would be a disaster, specially when there are tons of trolls trying to ruin Bitcoin out there.
