Hear, hear. Dogmatic adherence to any system is dangerous. It goes along with being dogmatic. It's important for developers to read what others have done, see how others have solved problems and stand on the shoulders of giants before thinking for themselves, instead of just blindly accepting "best practice" as the best practice.

What I like to do with TDD is use it whenever it's the quickest way to develop something with a level of confidence that is appropriate to the situation.

If I'm creating an HTTP API and someone else is writing the front-end, I'll create unit tests that spin up my API and make requests to it to ensure I get the correct responses.

If I'm in the middle of a codebase somewhere and there's a function which is only ever hit after a bunch of others things, I'll probably write a few tests for that, too.

Just like religious dogma, we are free to pick-and-choose what we do with TDD, when we feel it's most appropriate. Of course, don't overdo it to the point where the code suffers for it.
