Mine are mostly in the GOOD category but it's really for me, not the client. Like your clients, my clients trust me. But the benefit of listing the details is I can later go and analyze how much time I spent/wasted on which feature 6 months ago and give them a better idea on whether it will be better to keep trying to fix it or rewrite from scratch.

Having detailed info. also helps with knowing who requested/commissioned which task and when, without having to dig into emails, PM software etc.
