(2MB or just no) MAX BLOCK SIZE - uhhg not 100% - never been here ( Satoshis most important protocol param 1MB !)
If you think that BU is a simple change, or secure, you've been drinking some strong kool-aid. If I had to choose outside of Bitcoin Core, I'd go with the original Bitcoin Classic proposal (rather than the current Classic/BU nonsense).Here finally we might get feets on same ground - external / cross code rewieves ( core <-> BU ?) , dev testing and UAT / real live testing is your friend here.
That's why I'm close to some compromise thingy with SW and 4MB lift in a HF,
or Sergio Lerner comes up with the 3rd killer solution over midnight...
