Reducing the types of votes available would make getting my head around
them easier, certainly.
I think the 'lazy consensus' we have listed on our Wiki also conflicts
with the Apache version because of the -1 veto, which should certainly
be corrected; we should just link to the Apache page therefore.
Code changes by (Apache) lazy are already veto-able so it's just a small
change there.
Moving everything else from consensus to majority allows more stuff to
be approved more easily, which drives the project forward. I'm sure if
we got to the point of voting on something, and there were a large
fraction of -1 (but more +1) we'd still take that as a signal to
evaluate whatever it was more strongly.
