Yes. Wikis are meant to be a collaboration tool where anyone can edit pages. All edits are attributable and linked to a user with a work email address, so it is unlikely that a user would edit a page unless they had a good reason to do so. 

Also, the GCwiki keeps a history of all edits made on a page. If you don’t like a change someone has made, it’s easy to revert to an earlier version.
