I prefer to see consensus rules as one set of rules (especially
because they only really apply to blocks - the part for lone
transactions is just policy), and thus have a single numbering. Still,
I have no strong opinion about it and have now heard 3 'moderately
against' comments. I'm fine with using nVersion==2 for transactions.
