I'm also interested in your better source. Every book I've read on the subject and the top 4 search results on google say the same thing.
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.
If that's possible. What if there are some features for which it isn't?
I understand that testing tells you you broke the trunk, so you didn't break up the feature into small enough merge-able pieces. My question is what happens if you can't break it up any smaller--do you just throw up your hands and say you can't implement the feature because there's no way to break it up into small enough pieces?
With that said, I've been doing this for over ten years and haven't come across that scenario. You can easily figure out all kinds of tricks to break things down, but usually only after you believe in the value of it.
