Earlier quoted context omitted.
Defined structure does not constitute quality. A commit message can be loosely structured, but be very insightful and good at communicating the nature of the change. On the flip side, one can make a very structured but confusing or non-informative commit message. I generally tend to agree with the author, conventional commits do not solve the core issue of the poor commit messages problem.
why is "solving" the issue somehow the bar? software engineering has more practices rooted in psychology than engineering, its a moving and ambiguous target. Using conventional commits gives you a framework and mechanism that undoubtedly improves contribution semantics.
In what context does wasting your first characters on fix vs feat matter?
PRs are going to have an explanation that has way more detail than necessary to figure that out quickly.
One lines tend to be (for me) in a situation where the difference is immaterial. If I am rapid firing through history I need to know what you did not why you did it.
Again I am not claiming that these are bad or even that they aren't good.
I am specifically disagreeing that any change is automatically good, that isn't true.
