But at least you understand that BIP101 will increase the risk of centralization. However for SW proposal, I totally don't understand anything at all: By changing the bitcoin architecture, Pieter essentially change it to something else, an alt-coin. So all the talks about SW should go into alt-coin section, not here. And all this large degree of deviation from Satoshi's original design for what? A mere one time increase for capacity of light nodes, not even helping full nodes?
I've been quite surprised by your reaction to this proposal.
It's as if you're being intentionally obtuse because clearly you are making no effort at understanding SW and overexagerate its complexity.
Whether or not you agree with its motivations and underlying ideology SW is pretty straight forward.
