Am not sure I disagree but I don't agree completely. It's insane to merge things that go to production without testing. However at the same time I don't like continuous integration one bit. Open source mantra is great in my opinion. Release early, release often. If code chews some important data, have a test version of it that needs to run some time before it gets pushed to production.

Delaying merge of someone's code means branches get further and further apart. At the same time code in main branch gets fixed and tested the most. I would merge often but only full features. None of the half-done stuff. Let humans test it a bit before it reaches target audience. That is usually good enough to catch most bugs. Those that do happen to leak into production are easily fixed since you have fast development cycle and deployment pipeline. And backup frequently.
