Bull fucking shit. It turns fully-validating nodes into non-validating nodes.
A non-Segwit node can always validate transactions that are relevant to them. They do not validate the witness portion of Segwit transactions. They also do not generate Segwit addresses, nor do they participate in Segwit transactions. What you're talking about is moot.
What part of 'fully-validating node' do you not understand?
i think exstasie has been spoonfed by lauda or the people that spoonfed lauda.. because it seems that exstasie is saying the same illogical rhetoric as lauda and the motley crew he assoociates with, who are failing at convincing people that softforks do not effect true full node distribution count.
give it a few days and exstasie may also fail by saying that 'pruned and no witness archiving is no issue/risk to full nodes'. if so then he is obviously reading the 'Lauda script'
the more simpler explanation for them to see logic.. it to make it sound like a joke rather then a stab in the brain.
"when is a full-validating node not a full-validating node?.........."
