You are right ; we should continue. 20% of knots and 20% core 30 so 80 pct network running 80 capped op_return.
I would have preferred consensus to have capped op_return but the conservativeness in changing consensus is very important too (and, less so but also, the simplicity of consensus rules)
I disagree with changes implemented in relay policy by core. I believe it is reckless and arrogant. core has too much influence on the network through this type of changes I agree. But I am also happy that core can’t change consensus rules too easily.
I also want home solo mining to increase and I believe it will and we should aim for as much as possible designing own blocks through ocean
Then for BIP-110 itself I understand the motivation, the frustration etc, I am hesitating but it might be (at this stage at least) a bad precedent if it were to succeed and if does not reinforce core
