The general principal the author is talking about — ie not being overly opinionated— and asking yourself “Could I use this in combination with something else like it?” — could be applied to even something like a programming language. For example, Elm 0.19+ would be the counter-example in this case. It makes it very hard t/ almost impossible to interact with JS code. A more flexible web front-end wouldn’t force such a strong opinion upon its users. It would let the users decide, and leave flexibility / room in various aspects of the language.
