I wonder how this fits with the results from dora.dev that CI/CD is the most effective way to develop software. Is working on a single branch without feature branch and without mandatory code reviews even more effective? Or is it due to practices in CI/CD?

Maybe developers spend more time on reviewing and testing their code when they commit directly to the main branch, then when they know someone else is going to review tge code en perform the merge? How bad is a bug when it is caught the same day?
