So ABC + BU supports CDSVERIFY... It seems only CTOR is really controversial, CDSVERIFY controversy is made up by nChain.
Personally i dont see any problem with CDSVERIFY but i dont like ctor. csw dont want free choice.
I vote reject.
Prediction: Coingeek/nchain will orphan any block containing tx with CHECKDATASIG CDSVERIFY
