Have you taken the time to read any of the reference material? Have you looked at any of the actual data? Are you aware of how CD with trunk based development works?

You're making assertions that imply you haven't considered anything but your own bias. Your question only works if you have no understanding of how these things actual function

The goal is to reduce the amount of time it takes for a change to land in production. Your eight hour work day implies you have developers only in a single location too, instead of the distributed work force most of us have now.

You seem to be (blissfully?) unaware of how high performing organizations operate.
