How old are those documents? More recently, see http://www.plainlanguage.gov/howto/guidelines/bigdoc/writeContract.cfm https://lawyerist.com/61487/is-it-time-for-contractions-in-legal-writing/ The latter references other documents, which advocate for more use of contractions even in formal writing. > I personally don't feel too strongly about it, but the change > seems like an opportunity to improve not just the style of > the manual but also increase its consistency.

I think it's the wrong direction because I'd be in favor of gradually *introducing* contractions into to the manual instead of a change that eliminates them. I wouldn't be against a change that went in the other direction (used contractions consistently), but it would be good a large change, so I'm not advocating for doing that, but just instead using contractions in all new material and when modifying old material for other reasons.
