If you run WikiTrust on a dump, and you compute the "statistics", this gives you, for each revision, a score between -1 and +1, where: 
It also tells you how big the change was.  So, if you wanted to run this analysis on a dump, it would be failry trivial and fast (say, half a day for the Italian wikipedia?  One day for the German one?).  We would be happy to provide the details. 

Of course, this would just give you a measure of how much of each contribution is kept.  It would not tell you much about the intellectual contribution -- your adding a date for an event, will be judges as much as a bot adding a new category to the revision (both 1-word changes). 

But at least, it could be a quick start?  And more could be built on that?

I skipped over the part where you started by talking about bots. Sorry I was just thinking about the beautiful intellectual productivity that arises from revert wars between two human beings, at least for me.

Yes, it requires some synthetic variable, of which there are a few in the quant literature. (For example, Priedhorsky et al. defined a damaged article view (DAV).) However, it could be something as simple as what Spinellis and Louridas (2008) imply: a reversion is evidence of an unproductive contribution (ignoring revert wars for the moment), and so what percentage of all edits to WP are reverts? Has this changed over time.
