Why do you even want the issue number in the commit title? I find that super annoying and unfortunately GitHub kind of forces it on you if you use merge queues.
It's fine for it to be in the description.
It’s very helpful to know the motivation for the commit and if that motivation was tied to a client contract/feature. Especially in cases where a commit affects multiple files or even just one file so that all commits can be grouped into a feature/contract.
If i'm looking at git history, the ticket number is the most useful piece of info to get more context on the changes for me
