That's in a "Best Practices" section with this note at the top:

I'm not an expert, and I've read no books on the subject, so I'll refrain from suggesting sources. The implication of my comment was that it's disingenuous to use that link as proof when it's marked with the equivalent of a FIXME.
First off, I have no motive to be disingenuous. I really don't care how you collaborate on software with your team.
Secondly, CI itself is considered a best practice. I don't know how you could expect wikipedia to mark it as anything else?
Here's the top link from google if you really care to learn and aren't just here to be a contrarian: https://www.thoughtworks.com/continuous-integration . There is a wealth of information on this subject that I promise all says the same thing. We can argue about whether or not CI is useful, but the practice of integrating continuously is in all the literature as well as the name itself.
