Ah, I was thinking a different tactic: Everyone would just make mega-pages so that the page itself isn't stale but specific sections are. I think the best approach to this problem I've seen is an Last Edited date (or preferably, activity graph or "N" edits in the last year or similar) at the top that gets increasingly obnoxious as content gets more stale. Obviously far from perfect, but would have saved me from relying on out-of-date documentation many times.
