My belief is that in general we should be aggressive about removing vandalism from the page history. If there was an automated way to go through on a regular basis and remove reverted versions from the history, I would strongly support that we do so.
The only sensible counter-argument I know of in this area is a concern for future historians or contemporary researchers who would like to study the phenomenon of vandalism. For this, it seems more than enough to make such revisions available in some limited-access way. There's just no reason to keep this junk cluttering up the publicly-viewable article history.
