BTC is already the most decentralized money we've ever had. I'd hate to have my node fall out of consensus or see a chain split occur just because I was virtue signaling over MuH ImPleMeNtaTiOn sO sPeCiaL and CoRe Is CeNtRaLiZinG BTC

I don't think a chain split will happen if many people run knots because, like I said, its just core with extra options. But we've seen issues with implementations that aren't a direct fork of core like btcd (golang). If you were running btcd node when this happend... https://bitcoinmagazine.com/technical/bug-took-down-part-of-the-lightning-network

...then your node would have been kicked off the network, unable to get new blocks until patched. If thats the cost of being marginally more decentralized, then I don't think it's worth the tradeoff IMO. But run whatever node you want. It's not my problem if BTC rejects your node or you end up creating a shitcoin in the process.
