I appreciate that this will look like dodging your challenge, TTT, and that's partly because it is, but also I've procrastinated enough already today and doing the research needed to find the article(s) you're asking for will take a little bit of time. Hopefully I'll be able to find something later that'll satisfy you -- although, again, I am not sure what the point is other than to prove it's there.
I remember explaining the positive case for remaining on AB from a point of view of scientific research. Or, rather, trying to, since people either rejected it as irrelevant (this seemed odd, because this was in answer to the same basic question you are asking now), or just out-of-hand with no further explanation.
