It can work if you have a test zone and only a small amount of people work on a given code base.

Also checks to ensure the code compiles and tests pass before merging, as some quality gateway.

Something like that happened to me yesterday. I reviewed one PR, then some Important Guy came in and said:

• it is nice you reviewed my work, but we need to push this to production right now.
• just fix these things, I described you how. Just copy/paste these snippets
• these are cosmetics, I don’t care
• “cosmetics”, huh? Your shit may just crash
• gfy and push this to production right now
• well, ok

Of course, lack of these “cosmetics” caused crash in production. It’s my fault of course.

The “send it” school of PRs.
