My point is that commit messages should describe all this.

OK yes please add this informaiton into the comit log.

Also expand on it as to to *why* this was not a critical issue.

Just elaborate on the commit log. We cannot guess what is happening, and
so bringing clarity into exactly what you are doing and *why* is helpful
to determine the impact of not applying this.

This is crucial information to include in the commit log. When *would*
you use it? So that use case was broken since 2019? What negative
effects has this implicated?

The feedback is for you to improve the commit logs, not to tell you to
not do something. We cannot read your mind, and this smelled like a fix,
but without a true evaluation and documentation of the impact of not
having this in place. These things need to be thought out and written
in the comit log.

The commit log should clarify all this.
