My main complaint with conventional commits always was that they don't include an issue number in the commit title. It's not even mentioned in their standards as optional or something.

To me this is almost the most important information in a commit message. I don't know how often in the last 15 years I was cross checking the issue description referenced by some old commit to get the full context of a change. I also felt that this habit is kind of standard - until i had to learn about "conventional commits".

I never got the hype.
