This is just the classic rehash of are comments in code an anti-pattern.

I tend to agree that at a certain point if you need to constantly think "gee, I wish I was in the meeting when they came up with this" the code you are looking at might just suck.

In such contexts it is also often the case that being in the meeting may not have helped. As they say, garbage in, garbage out.

Sometimes it is useful to simply know something was brought up, but then someone had a sneezing fit and everyone lost track of the thread and the important edge case under discussion just fizzled.

A similar thing happens in agentic conversations, where a model may point out something but it is not recognized as important by the operator.

A few directives later and the model is being pushed another direction.
